Archie provides information about files available for ftp anywhere on the Internet; Xarchie displays this information using an easy-to-use, point-and-click interface. Xarchie allows you to further explore ftp sites by examining directories returned as query matches, and allows you to retrieve files located this way. Xarchie is designed (like most X applications) to be highly customizable, allowing you to tailor the look-and-feel of the tool to your own preferences. This document is broken into two parts. First, the USER'S GUIDE describes Archie and Xarchie, and covers both Basic and Advanced Xarchie usage. Second, the REFERENCE MANUAL provides all the information needed to customize Xarchie. You can also browse this document using the Xarchie Help facility. To report problems or bugs, please see the section "Reporting Bugs" in the REFERENCE MANUAL section. UUUUSSSSEEEERRRR''''SSSS GGGGUUUUIIIIDDDDEEEE The User's Guide section of this manual describes the Archie service, the Xarchie client, and how to use Xarchie to access resources available for FTP on the Internet. WWWWhhhhaaaatttt iiiissss AAAArrrrcccchhhhiiiieeee???? The Archie information system is a network-based information tool offering proactive data retrieval and indexing for widely distributed collections of data. Perhaps the best known application of the Archie system is to maintain the Internet Archives database. This database, already available from a number of service providers across the Internet, currently contains the names of over 2,100,000 files at over 1,000 anonymous FTP archive sites. Using this database, users can rapidly locate needed files without the need to log onto dozens or even hundreds of machines. Archie servers offering this database currently receive over 50,000 queries per day. It is this database that the Xarchie Page 1 (printed 6/30/95) XXXXAAAARRRRCCCCHHHHIIIIEEEE((((1111)))) UUUU ooooffff RRRRoooocccchhhheeeesssstttteeeerrrr ((((22224444 AAAAuuuugggg 1111999999993333)))) XXXXAAAARRRRCCCCHHHHIIIIEEEE((((1111)))) client accesses, as described in the next section, using one of the many independently owned and operated Archie servers around the world. The Archie system is much more than the Internet Archives database. For more information contact Bunyip Information Systems at (514) 398-3709 or (514) 398-811 or email "info@bunyip.com". WWWWhhhhaaaatttt iiiissss XXXXaaaarrrrcccchhhhiiiieeee???? Xarchie is an X11 browser interface to the Archie Internet Archives database using the Prospero virtual filesystem protocol. Archie provides information about files available for ftp anywhere on the Internet; Xarchie displays this information using an easy-to-use, point-and-click interface. Xarchie allows you to further explore ftp sites by examining directories returned as query matches, and allows you to retrieve files located this way. Xarchie is designed (like most X applications) to be highly customizable, allowing you to tailor the look-and-feel of the tool to your own preferences. See the REFERENCE MANUAL for details. Users should be aware that the Xarchie client accesses a server that is shared with users on other hosts. As such, submitting long or large numbers of queries during peak periods not only increases the time that you have to wait for a response, but it increases the time that others have to wait too. Please read about the -_n_i_c_e option, the nnnniiiicccceeeeLLLLeeeevvvveeeellll resource, and the "Nice Level" setting before making large queries. Also, you should use the closest possible host to save long-distance network traffic. Abusers of the service may find their access revoked without notice. TTTThhhheeee XXXXaaaarrrrcccchhhhiiiieeee DDDDiiiissssppppllllaaaayyyy Xarchie uses several conventions regarding menus and button names: - Clicking on a button whose name ends with a ">" will pop up a menu from which you should select the desired action. - Clicking on or selecting an item whose name ends in "..." will pop up a panel that will let you perform the desired operation. A label with neither of these suffixes indicates that the action will be taken without subsequent interaction. Xarchie's display is divided into three horizontal areas. The top pane is a control panel providing the following Page 2 (printed 6/30/95) XXXXAAAARRRRCCCCHHHHIIIIEEEE((((1111)))) UUUU ooooffff RRRRoooocccchhhheeeesssstttteeeerrrr ((((22224444 AAAAuuuugggg 1111999999993333)))) XXXXAAAARRRRCCCCHHHHIIIIEEEE((((1111)))) buttons: File: Clicking on this button presents the File Menu, from which you can select a variety of file-related operations to be described later. The File Menu operations can also be invoked by holding down the Meta key and typing the first letter of the operation's name (e.g., Meta-Q to quit). Settings: Clicking on this button presents the Settings Menu, whose operations will be described in the "Advanced Usage" section. Query: This button presents the Query Menu, used to send queries to Archie. Its operation will be described shortly. Abort: When active during a query or retrieval, this button allows you to abort the operation. Help: Clicking on this button pops up the Help Panel, which allows you to browse this document on-line. Finally, the area labelled "Status" is used to provide information about the progress of a query or other informative messages. The middle pane of the Xarchie display functions as a host- location-file browser. That is, the leftmost pane displays hostnames, the middle pane locations (directories), and the rightmost pane files or directories returned by a query. The browser's use is described in the section "Browsing", below. You can adjust the relative size of the browser panes using the Grips on their borders. Finally, the bottom pane of the Xarchie display provides a set of Text items where you can enter information and where information is displayed as query results are browsed. Not all Text items can be typed in; some are used for display only. These text items provide Emacs-like editing controls (see _x_e_d_i_t(1) for a complete description). Typing Return in some Text items invokes an action as a shortcut for selecting it from a menu or button. BBBBaaaassssiiiicccc XXXXaaaarrrrcccchhhhiiiieeee UUUUssssaaaaggggeeee This section provides information on basic querying, browsing, and file operations. The "Advanced Xarchie Usage" Page 3 (printed 6/30/95) XXXXAAAARRRRCCCCHHHHIIIIEEEE((((1111)))) UUUU ooooffff RRRRoooocccchhhheeeesssstttteeeerrrr ((((22224444 AAAAuuuugggg 1111999999993333)))) XXXXAAAARRRRCCCCHHHHIIIIEEEE((((1111)))) section describes how to use the Settings Panel and how to perform other, more complicated, queries. QQQQuuuueeeerrrryyyyiiiinnnngggg The primary function provided by Xarchie is that of querying the Archie server for a "search term" (the string or expression for which you want to search). By default, your query uses _e_x_a_c_t search mode. That is, the search term must literally match an entry in the database for the entry to be returned. Other search modes are available, and are described in the "Advanced Usage" section. You enter your search term in the appropriately labelled Text item in the bottom pane of the Xarchie display. Hitting Return in the text item or selecting "Query Item" from the Query Menu will send your request to Archie. The Status area will be updated as the query progresses. First the Archie server's Internet address is looked up, then the server is contacted, the search term is sent over, and, after reaching the front of the server's request queue, matches are returned to Xarchie. The matches, if any, are displayed in the browser and the Status area indicates how many matches were returned. If your window manager and version of X support it, you can iconify the Xarchie application and the icon will change to reflect the progress of your query. That is, it will change when a query is in progress and when it finishes. AAAAbbbboooorrrrttttiiiinnnngggg If you find that your query is taking too long, you can abort it by clicking on the "Abort" button when it is active. Your query will be aborted as soon as possible. You should note that while aborting a query will allow you to enter a new query, it does not remove the query from the server's queue (this may be changed in the future). Thus aborting queries does not reduce the load on the server -- just the opposite probably. Use it with discretion, like the rest of the service. BBBBrrrroooowwwwssssiiiinnnngggg As described in the section "The Xarchie Display", the middle pane of the Xarchie display functions as a host- location-file browser. The leftmost pane of the browser contains the names of hosts that have a file matching your search term. Clicking the Left mouse button on a hostname will highlight it and cause the middle browser pane to be filled with a list of locations on that host where files matching your search term can be found. The selected hostname will also be displayed in the Text item labelled "Host" in the bottom pane of the Xarchie display. Page 4 (printed 6/30/95) XXXXAAAARRRRCCCCHHHHIIIIEEEE((((1111)))) UUUU ooooffff RRRRoooocccchhhheeeesssstttteeeerrrr ((((22224444 AAAAuuuugggg 1111999999993333)))) XXXXAAAARRRRCCCCHHHHIIIIEEEE((((1111)))) Similarly, selecting a location from the middle browser pane will cause the right browser pane to be filled with a list of the files available from the selected host in the selected location, and the location will be displayed in the bottom pane item labelled "Location". Finally, selecting a file from the right browser pane causes its name, size, permission modes and last-modification date to be displayed in the correspondingly-labelled bottom pane items. Note that if a browser pane has only one item, then that item will be automatically selected and its "lesser" panes and information items filled in. This saves time and effort in the common case where there is only one host, location, or file that matches your query. Also, note that, by default, Xarchie scrolls the browser pane when you select an item. This makes it easy to click through a long list of matches, but can be annoying. If you don't like it, it can be changed on the Settings Panel (described below), and see the description of the ----nnnnoooossssccccrrrroooollllllll command-line option in the REFERENCE MANUAL. The browser allows you to select multiple items simultaneously, although of course only the last-selected item will have it's information displayed in the bottom pane. You add to a selection by clicking the Left button with Shift depressed. If the clicked-on item is already selected, it will be unselected. Currently, only the bottom level of the browser can have multiple selections, since a selection at a higher level clears the selections for all lower levels (this may be changed in the future). Thus you can select multiple files from a single host, but not multiple files from separate hosts. EEEExxxxppppaaaannnnddddiiiinnnngggg tttthhhheeee BBBBrrrroooowwwwsssseeeerrrr The browser can be expanded, allowing you to investigate, say, a directory that matched your query. To select and expand an directory, double-click on it (double-click with Shift to avoid unselecting any other items). You can also select "Open" from the File Menu to expand directories (although this will also open selected files, as described later). All selected directories will be expanded by querying an appropriate Archie server, and the Status area will keep you informed. Expansion requests can be aborted just like queries using the "Abort" button. If only a single item was expanded, and if the expansion was successful, then the browser will scroll to display the results. The arrow buttons across the top of the browser can be used to scroll the browser left or right when they are active. The Middle and Right mouse buttons or the Left and Page 5 (printed 6/30/95) XXXXAAAARRRRCCCCHHHHIIIIEEEE((((1111)))) UUUU ooooffff RRRRoooocccchhhheeeesssstttteeeerrrr ((((22224444 AAAAuuuugggg 1111999999993333)))) XXXXAAAARRRRCCCCHHHHIIIIEEEE((((1111)))) Right arrow keys will do the same thing, when the pointer is in the browser panes. VVVViiiieeeewwwwiiiinnnngggg FFFFiiiilllleeeessss You can view a file that is selected in the browser by selecting "Open" from the File Menu (or by typing Meta-O). Xarchie retrieves all selected files in ASCII mode into a temporary directory. The Status area, like usual, will keep you posted on the progress of the operation and, once the FTP connection is established, the Abort button can be used to abort the Open operation. If you abort and there are files remaining to retrieve, you will be prompted as to whether to continue with the next file. Note that partially-retrieved files are not removed. There is currently no way to abort the transfer until the connection is established. The connection will eventually timeout and control will return to Xarchie if connection is impossible. Each file is displayed in a popup Text window after being retrieved. Use the "Down" and "Up" buttons or the scrollbars to view the text. Click on the "Dismiss" button to destroy the window and delete the file. To save the file before dismissing, use the "Save" button. This pops up a panel with which you can choose the name of the file to which to save. Note that because the Archie database is only updated periodically, some files returned by Archie may not exist when you attempt to retrieve them. This and any other FTP errors are signalled with alert boxes. RRRReeeettttrrrriiiieeeevvvviiiinnnngggg FFFFiiiilllleeeessss The "Open" action should be used to view short files, such as "README" files, that you don't need to save. For more permanent files, and for non-ASCII files like tar or compressed files, Xarchie allows you to retrieve the selected browser items using the "Get" item of the File Menu (or typing Meta-G). The selected files are retrieved via FTP and stored in the current directory (see the section "FTP Parameters" in the "Advanced Usage" section for how to change this). The "Status" area is updated to reflect the progress of the transfer. As for "Open", you can abort the retrieval using the "Abort" button once the FTP connection is established. It is currently not possible to retrieve a directory, although of course the directory can be opened and the entire contents selected for transfer. Note that because the Archie database is only updated periodically, some files returned by Archie may not exist when you attempt to retrieve them. This and any other FTP Page 6 (printed 6/30/95) XXXXAAAARRRRCCCCHHHHIIIIEEEE((((1111)))) UUUU ooooffff RRRRoooocccchhhheeeesssstttteeeerrrr ((((22224444 AAAAuuuugggg 1111999999993333)))) XXXXAAAARRRRCCCCHHHHIIIIEEEE((((1111)))) errors are signalled with alert boxes. As with querying, if your window manager and version of X support it, Xarchie's icon will be changed to reflect the progress of a transfer. SSSSaaaavvvviiiinnnngggg,,,, LLLLooooaaaaddddiiiinnnngggg,,,, aaaannnndddd WWWWrrrriiiittttiiiinnnngggg Xarchie allows you to save and reload the contents of the browser, or write it in human-readable format using the items on the File menu. Selecting either of "Save", "Load", or "Write" (or typing Meta-S, Meta-L, or Meta-W, respectively) will pop up the File Panel with which you can specify the appropriate filename. Clicking on the "Ok" button will invoke the appropriate action; clicking "Cancel" will abort the operation and pop down the panel. Saving the database creates a file containing sufficient information for the browser to be reloaded using "Load". The output is not intended for human consumption. The current Settings are also written to the file by "Save" and are restored by "Load". Users should note that a reloaded database will be "flattened", that is, directories will be added to the middle pane as needed to fit everything in three browser panes. (This may be changed in the future to preserve the original hierarchy.) Writing the database is intended to create files that are more or less human-readable (compared to "Save", anyway). There are two possible formats, selectable from the "Write Format" menu on the panel. If "One entry per line" is selected, then the output will have one line per entry, in the format mode size date host:location/file If "Pretty-printed" is selected, then the file format has hostnames starting at the beginning of the line, location names indented one tab, and file entries indented two tabs, all on separate lines. Hostnames and locations are only printed once, as in: host location mode size date file mode size date file The latter is more readable, the former may be more useful if the output is to be used by a program. QQQQuuuuiiiittttttttiiiinnnngggg XXXXaaaarrrrcccchhhhiiiieeee PPPPaaaaggggeeee 7777 ((((pppprrrriiiinnnntttteeeedddd 6666////33330000////99995555)))) XXXXAAAARRRRCCCCHHHHIIIIEEEE((((1111)))) UUUU ooooffff RRRRoooocccchhhheeeesssstttteeeerrrr ((((22224444 AAAAuuuugggg 1111999999993333)))) XXXXAAAARRRRCCCCHHHHIIIIEEEE((((1111)))) You can exit Xarchie by selecting "Quit" from the File Menu (or typing Meta-Q). AAAAddddvvvvaaaannnncccceeeedddd XXXXaaaarrrrcccchhhhiiiieeee UUUUssssaaaaggggeeee This section describes how various aspects of Xarchie's functionality can be modified to perform different queries and other operations. Further customization information is found in the REFERENCE MANUAL section. TTTThhhheeee SSSSeeeettttttttiiiinnnnggggssss PPPPaaaannnneeeellll The panel popped up by selecting "Other" on the Settings Menu in the top Xarchie pane allows you to change the parameters of your queries Archie. Each of the parameters is described in the following sections. After you're done with the Settings Panel, clicking on the "Apply" button will make Xarchie use the settings as set on the panel. Clicking on "Default" will reset the settings to the values they had when Xarchie started (but note that you will still have to apply them to have them take effect). Clicking on "Done" closes the Settings panel. A popup confirmer will appear if you did not apply your changes, allowing you to discard the changes or go back and apply them. Note that the "Apply" button is inactive until a change is made. The menus available from the "Search Type", "Sort Type", "Nice Level" and "Archie Host" submenus of the Settings Menu on the Xarchie top pane have effects corresponding to those of the buttons on the Settings Panel. However, they do not require that the "Apply" button be clicked on to take effect, and do not affect the behaviour of the "Done" button confirmer. AAAArrrrcccchhhhiiiieeee hhhhoooosssstttt The item labelled "Host" provides a menu of known Archie hosts. You should choose one appropriate to your site (i.e., one that minimizes long-distance transmission). In addition however, you can enter an arbitrary hostname in the Text item next to the "Host" button. Note that the Archie host is only used for queries; expansion requests use information stored with the items to determine which host to contact. That is, changing the Archie host does not "take effect" until the next query is issued. If you have the _p_i_n_g(1) program, you can try to use it with the its "-s" option to locate a "nearby" host. You can specify hostnames using either the symbolic name or by giving its numeric IP address (four octets separated by periods). In either case, you can specify the port at which the Prospero server should be contacted by giving it in Page 8 (printed 6/30/95) XXXXAAAARRRRCCCCHHHHIIIIEEEE((((1111)))) UUUU ooooffff RRRRoooocccchhhheeeesssstttteeeerrrr ((((22224444 AAAAuuuugggg 1111999999993333)))) XXXXAAAARRRRCCCCHHHHIIIIEEEE((((1111)))) parentheses immediately following the hostname (no spaces). SSSSeeeeaaaarrrrcccchhhh mmmmooooddddeeee The "Search Mode" item allow you to change how Archie interprets your search term. Holding a mouse button down while the mouse cursor is on the button displays a menu from which you can choose the desired search type. The label to the right of the item is updated to reflect the choice. The _e_x_a_c_t mode is fastest and returns files exactly matching your search term. The _s_u_b_s_t_r and _s_u_b_c_a_s_e modes return substring and case-sensitive substring matches respectively (i.e., _s_u_b_s_t_r means case-insensitive). The _r_e_g_e_x_p mode allows you to specify a regular expression to select files (see _e_d(1) for a description of regular expression syntax). The _e_x_a_c_t* forms of these last three try an exact match first and then fall back on the more costly search type if the exact match fails. SSSSoooorrrrtttt mmmmooooddddeeee The "Sort Mode" item allows you to specify how Xarchie displays the results from Archie. Holding a mouse button down while the mouse cursor is in this item displays a menu from which you can choose the desired sort type. The label to the right of the item is updated to reflect the choice. Applying the settings (see above) will cause the data to be resorted according to the new sort mode. The type can be one of _n_a_m_e, _d_a_t_e, or _w_e_i_g_h_t. Sorting by _n_a_m_e is simple lexicographic ordering. If sorting by _d_a_t_e is selected, then hosts are ordered according to the most recent file among those returned for them, and similarly for locations. Files themselves are ordered by last-modification date, naturally. If sorting by _w_e_i_g_h_t is selected, then hosts are ordered by a user-definable set of "weights". In this way, hosts that are "close" (in some sense) are displayed first. The weights can be set using the Text item that appears on the Settings Panel when this sort mode is selected. Hopefully, an appropriate weight list for the geographic location of your site will have been installed as the default. In any case, the the weight list is a set of lines, where each line specifies a weight and the set of domains for that weight. A host's weight is determined by finding the first line for which the end of the host's name matches one of the suffixes. A host that belongs in none of the classes is assigned the weight 99. For example, the default for the USA is: Page 9 (printed 6/30/95) XXXXAAAARRRRCCCCHHHHIIIIEEEE((((1111)))) UUUU ooooffff RRRRoooocccchhhheeeesssstttteeeerrrr ((((22224444 AAAAuuuugggg 1111999999993333)))) XXXXAAAARRRRCCCCHHHHIIIIEEEE((((1111)))) 1 edu com net gov mil us\n\ 2 ca\n\ 3 uk de nl fi fr eu.net\n\ 100 au nz jp This means that all the US domains are ordered first, then Canada, then several European countries. Hosts in Australia, New Zealand, and Japan are ordered _a_f_t_e_r any unknown (i.e. non-matching) hosts. For more details, see the description of the hhhhoooossssttttWWWWeeeeiiiigggghhhhttttssss non-widget resource in the REFERENCE MANUAL section. NNNNiiiicccceeee lllleeeevvvveeeellll The "Nice Level" item deserves special mention. As mentioned in the "About Archie" section, Archie servers run on machines that must be shared between other Archie users and even other "real" users. This item allows you to voluntarily lower the priority of your request, just like the _n_i_c_e(1) command does for Unix. The menu provides some recommended values and you can enter arbitrary values in the text item. If you are searching with a large number of matches requested, please increase your nice level. Note that, like _n_i_c_e(1), nicing a job does not mean your job won't affect others. In particular, once your job begins it is not pre-empted, thus you should still avoid long jobs during peak periods. You should especially avoid queries for items of only personal interest (you know what we mean) during these periods. As stated above, abusers of the service may find their access revoked without notice. OOOOtttthhhheeeerrrr QQQQuuuueeeerrrryyyy SSSSeeeettttttttiiiinnnnggggssss The following items set parameters of your query to the Archie server. Max Hits: the limit on the number of successful matches that will be returned. Initial Timeout: the length of the first timeout interval in seconds. Retries: the number of times to retry a query if it times out, doubling the timeout each retry. These items are Text items that allow you to edit their values. The item labelled "Auto-Scroll Browser" controls whether the browser scrolls after an item is selected. Setting this to Page 10 (printed 6/30/95) XXXXAAAARRRRCCCCHHHHIIIIEEEE((((1111)))) UUUU ooooffff RRRRoooocccchhhheeeesssstttteeeerrrr ((((22224444 AAAAuuuugggg 1111999999993333)))) XXXXAAAARRRRCCCCHHHHIIIIEEEE((((1111)))) "yes" is useful when browsing a long list of matches. It can be annoying if you're doing more selective browsing, so set it to "no" in those cases. FFFFTTTTPPPP sssseeeettttttttiiiinnnnggggssss The following items allow you to set parameters of file retrieval. You should be sure they are appropriately set before retrieving files using either "Open" or "Get". FTP Email Address: Specifies the password used for anonymous FTP login. By convention, users logging in as "anonymous" send their email address as the password. Some servers enforce this by checking the address. The default may not be appropriate depending on what information Xarchie could glean from your system about its address. You can set the environment variables UUUUSSSSEEEERRRR and HHHHOOOOSSSSTTTTNNNNAAAAMMMMEEEE to override the system's information, or see the description of the ffffttttppppMMMMaaaaiiiillllAAAAddddddddrrrreeeessssssss non-widget resource in the REFERENCE MANUAL. FTP Local Directory: Specifies the directory into which files will be retrieved using "Get". FTP Transfer Type: Provides a menu from which you can select "ascii" or "binary" mode transfer for files retrieved with "Get". Files retrieved with "Open" are always retrieved in ascii mode. FTP Prompt: Provides a menu allowing you to enable or disable prompting during multi-file transfers. Trace FTP Transfers: Since FTP transfers are susceptible to timeouts and other confusions, this item allows you to monitor any FTP interactions. If tracing is enabled, then invoking "Open" or "Get" on a file will popup a trace window that displays a running log of the FTP session as it happens. Using this successfully requires that you understand something about how FTP works, which is beyond the scope of this document. Strip CR If this option is enabled, then carriage returns are removed from ASCII-mode files. This is usually desirable when transferring to a Unix machine. QQQQuuuueeeerrrryyyyiiiinnnngggg HHHHoooossssttttssss aaaannnndddd LLLLooooccccaaaattttiiiioooonnnnssss The Query Menu provides two other types of queries besides Page 11 (printed 6/30/95) XXXXAAAARRRRCCCCHHHHIIIIEEEE((((1111)))) UUUU ooooffff RRRRoooocccchhhheeeesssstttteeeerrrr ((((22224444 AAAAuuuugggg 1111999999993333)))) XXXXAAAARRRRCCCCHHHHIIIIEEEE((((1111)))) the "Query Item" described in the "Basic Usage" section for querying the Archie database. Selecting "Query Host" will use the hostname in the "Host" Text item on the bottom pane and will fill the browser with the contents of the root of its FTP directory. From then on, interaction is as previously described. The host to query can be in the "Host" item as a result of selecting a host in the browser, or you can type directly into the item the name of the host that you wish to open. Typing Return in the "Host" item is equivalent to selecting "Query Host" from the Query Menu. Querying locations by selecting "Query Location" is similar: the Archie server is queried for the contents of the directory given by the "Location" item on the host given by the "Host" item. The browser is filled in with the results of the query (i.e., the contents of the directory). As before, you can type the name of the location into the "Location" item if you wish, and typing Return there is the same as invoking "Query Location". Note that because the Archie database is only updated periodically, some files returned by Archie may not exist when you attempt to retrieve them. Similarly, recently added files may exist on the host but not in the Archie database. RRRREEEEFFFFEEEERRRREEEENNNNCCCCEEEE MMMMAAAANNNNUUUUAAAALLLL This section provides all the information you should need to customize Xarchie.

A host's weight is determined by finding the first class for which the end of the host's name matches one of the suffixes. A host that belongs in none of the classes is assigned the weight 99. For example, the default for the USA is: 1 edu com net gov mil us\n\ 2 ca\n\ 3 uk de nl fi fr eu.net\n\ 100 au nz jp This means that all the US domains are ordered first, then Canada, then several European countries. Hosts in Australia, New Zealand, and Japan are ordered _a_f_t_e_r any unknown (i.e. non-matching) hosts. This resource can be set on the Settings Panel.

This allows resources that are only applicable for color displays to use the prefix "Xarchie.color" while generally applicable resources should use the "Xarchie*" prefix. On gray-scale displays, the extra widget is named "gray". On monochrome displays, no extra widget is created. The XfwfMultiList widget is a modification of the standard Athena List widget that allows multiple items to be selected. It was written by Brian Totty (totty@flute.cs.uiuc.edu) and is distributed by the Free Widget Foundation (contact free-widgets- request@kazoo.cs.uiuc.edu). _X_a_r_c_h_i_e can be compiled to use standard Athena List widgets instead.

The menus are all children of the main Xarchie shell, _t_o_p_l_e_v_e_l. For example, the File menu has widget hierarchy SimpleMenu fileMenu SmeBSB menuLabel SmeBSB fileMenuItem{0,1,2,3,4,5,6} There are three things worth mentioning.

The Settings Panel menus (the second group) only update the Settings panel, requiring the Done button to be clicked to take effect. The Settings menu submenus (the first group) take effect immediately, and also indicate the current item in the left margin of the menu. Finally, the number, order, and effect of all menus are hardcoded, although the labels can, of course, be changed in the resource file. However, changing the labels will NOT change the effect of selecting the item, with the exception of the _h_o_s_t_M_e_n_u and _s_e_t_H_o_s_t_M_e_n_u. These menus use the _n_u_m_H_o_s_t_s non-widget resource to indicate how many items are on the menu. Thus you can add hosts to the menu by adding _l_a_b_e_l resources for the new _h_o_s_t_M_e_n_u_I_t_e_m's and increasing the value of _X_a_r_c_h_i_e._n_u_m_H_o_s_t_s. Xarchie parses the labels to determine the hostname: anything up to whitespace constitutes the hostname (and optional port number), anything after is simply commentary.

First, and by far the most likely, is that the server is simply busy. Try again later. The other possibility is that UDP traffic is disabled on your system.

KKKKnnnnoooowwwwnnnn BBBBuuuuggggssss Crashes have been observed when the Help text is scrolled. There is no fix, but see the PROBLEMS file for some discussion. The list of files in the FileChooser widgets don't seem to get displayed properly all the time. That is, sometimes items seem to be drawn on top of each other. Refreshing the window (eg., iconify/deiconify or scrolling up/down) clears it up. This seems like an Xaw bug, but is difficult to repeat in isolation. Your mileage may vary regarding the Xarchie icon changing to reflect search and transfer status. Your window manager may not support application-specified icons, or may not support them changing dynamically. See the PROBLEMS file for some discussion. It is not currently possible to abort during nameserver lookup. Perhaps some day I'll get motivated to add asynchronous DNS code. The browser has a hard-coded maximum depth, beyond which you cannot expand directories. I don't think it will be a major problem however.
