- Quick Start:
-
- For people who hate reading entire documentation files
- just to find out what a program does, this compressed
- file contains a program that will merge Blue Wave mail
- packets so that you can keep important messages in a
- format where they are easily used and found. The command
- line options can be displayed by running BWSAVE.EXE with
- no other options, or with /?.
-
-
- Installation:
-
- Installation of BWsave is simple, just decompress the
- executable file (BWSAVE.EXE) into a subdirectory that is
- on your DOS path or other similarly convenient place.
-
-
- Operation:
-
- BWSave takes several command line arguments to control
- its operation. Two are required, and the other four are
- optional and modify BWSave's operation. The two required
- parameters are the source and destination mail packet
- names. The source packet is the one that you have that
- you want messages saved from, and the destination packet
- is where those messages are going. The destination packet
- name must be the last file name on the command line. If
- the destination packet does not exist, BWSave will create
- it for you.
-
- In its simplest use, the command line:
-
- BWSAVE CONNECTN.SA1 CONNECTN.999
-
- will uncompress CONNECTN.SA1 and CONNECTN.999 to
- temporary directories, add messages marked for saving in
- CONNECTN.SA1 to the packet in CONNECTN.999 and recompress
- CONNECTN.999. If CONNECTN.999 does not exist, BWSave will
- create it.
-
-
- Command Line Options:
-
- BWSave has four optional command line options that change
- its default behaviour (save all messages marked 'Save').
- They are:
-
- /all This causes BWSave to copy all messages
- from the source packets to the
- destination packet, regardless of the
- status of the 'Save' attribute.
-
- /conf='AT' This switch causes BWSave to copy all
- messages from the conference specified by
- 'AT' (the area tag) to the destination
- packet regardless of the status of the
- 'Save' attribute.
-
- /noinf Causes BWSave not to copy the
- BBS_NAME.INF file to the destination
- packet. (See "Bugs", below.)
-
- /unread This causes BWSave to mark each message
- it saves to the destination packet as
- having not yet been read.
-
- The Area Tag (for the /conf= switch) depends on the BBS
- software in use. It is a string of characters that the
- BBS uses to keep track of the various message areas
- available. On bbs software that uses the 'Hudson' message
- base (Remote Access, QuickBBS, etc.), this is a number
- from "1" to "200" and would be used like /conf=200 or
- /conf=32. On other software (like Telegard), the area tag
- is a name, like C_ECHO, or RA_UTIL, which would be used
- as /conf=C_ECHO. The comparison is not case sensitive, so
- /conf=c_echo would also work.
-
- The easiest way to discover what Area Tag your favourite
- message area has is to check from within Blue Wave. There
- are two places that this information can be displayed,
- the 'Area to Read' screen, and while reading a message in
- the area. From the 'Area to Read' screen, highlighting a
- message area and pressing the <Tab> key will display a
- box with information about the message area that looks
- like:
-
- ┌─ Current Area Information ────────────────────────────┐
- │ Main │
- │ (Local Base) │
- │ Area Tag : 1 │
- │ Msg Types : Public and Private Msgs Allowed │
- │ Name Used : David Gersic │
- │ │
- │ Total Msgs: 8 Unread Msgs: 0 Personal Msgs: 0 │
- └───────────────────────────────────────────────────────┘
-
- While reading a message in the conference, the <I> key
- presents a similar box.
-
- In either case, the Area Tag line displays what the BBS
- is using, and what should be specified with the /conf=
- switch.
-
- The command line switches are treated as a logical 'OR'
- during BWSave's processing. BWSave will copy a message to
- the destination packet if it is marked 'Save' OR if
- '/all' is in effect OR if /conf= is in effect and the
- current message is in the specified conference.
-
- BWSave also now has the ability to handle more than one
- source packet at a time. Multiple packet names can be
- passed to BWSave on the command line (the last file name
- on the command line is assumed to be the destination
- packet name), either individually or via DOS wildcards.
- BWSave will decompress the destination packet, decompress
- each source packet, add the messages from the source
- packets, and recompress the destination packet after all
- source packets have been processed. With a large
- destination packet and many source packets, this can be
- quite a time saver.
-
- Warning: you should specify a valid Blue Wave packet file
- name for the save packet name. BWSave doesn't care what
- you name it, but Blue Wave will only "see" correct file
- names.
-
-
- Speed: From my own testing, most of BWSave's processing
- time is spent shelling to the archiving programs. A good
- disk cache does speed up BWSave's operation, though, as
- it is disk intensive. I use, and recommend, HyperDisk,
- but others like SmartDrive, NCache, or PC-Kwik should
- work.
-
-
- Bugs:
-
- As far as I know, there are no actual bugs in BWSave, but
- there are a few potential bits of wierdness.
-
- First, BWSave makes no attempt to keep you from saving
- the same message twice. This can lead to a saved message
- packet with duplicate messages in it if you accidentally
- BWSave the same source packet more than once. Fortunatly,
- Blue Wave can delete messages from mail packets, so this
- is only a minor annoyance.
-
- Second, any changes in the message areas on the bbs may
- produce strange results once a new packet is merged with
- an older one. The symptom of this is messages "moving"
- from one message area to another. If you notice that all
- of your saved messages in the "NETMAIL" area just moved
- to "SWEEDISH_COOKING", you'll know that your sysop has
- been rearanging his message areas. The simplest recovery
- from this is to replace the BBS_NAME.INF file in your
- saved mail packet with one from an older mail packet.
- Note that this is not the same as the BBS_NAME.INF file
- in your Blue Wave directory. The /noinf switch will keep
- BWSave from undoing your fix the next time you save
- messages to your destination packet. Other than start a
- new save packet, or live with your NetMail being listed
- as being in the Sweedish_Cooking echo, there isn't much
- you or I can do about this.
-
- Third, I detect the type of archiver used to compress the
- mail packet, but only Zip, LHA, ARJ, and Pak format
- archives can be handled. Any other archiver will give you
- an error message. If somebody wants to NetMail me the
- command lines that should be used for Zoo, ARC, and ARC6
- formats, I'll be happy to add them. Archiver detection
- may not be perfect, either, as I only use and tested Zip,
- LHA, and ARJ.
-
- Fourth, BWSave assumes that it can find your archive
- utilities on your DOS PATH, and that they are named
- PKZIP/PKUNZIP, LHA, or ARJ. If you have renamed them,
- BWSave will not be able to find them and may work in
- strange and wonderous ways.
-
-
- Legal Caveats:
-
- While I have tried my hardest to develop and test this
- software to ensure that there are no bugs in it, I make
- no claim that it is perfect. If any bugs are found, I
- would appreciate a report of them, but I take no
- responsibility for any damage they may do.
-
- This software is copyrighted material. It may be
- distributed freely, but only in complete and unmodified
- form. If you are going to use it regularly, you must
- register it. As this is a simple utility that I wrote
- because I wanted one, I'm only asking for $5. If it isn't
- worth $5 to you, delete it from your disk. Remember,
- shareware only works if you pay.

-
- Ray Gardner, for a much faster insertion sort than I
- could write.
-
- Michael Tatum and George Worley for pointing out a few
- bugs that I missed in version 1.0.
-
- George Worley for pointing out a bug in 1.1, also.
-
-
- New in version 1.1:
-
- Deleting all of the messages in a message area was
- confusing BWSave which would then run out of memory
- trying to add a new message to the saved packet; fixed.
- Only about 120 messages could be saved; fixed. I tested
- saving up to over 1600 messages and had no problems with
- BWSave or Blue Wave handling the packet.
-
-
- New in version 1.2:
-
- BWSave was producing a <BBS Name>.MIX file that the Blue
- Wave reader couldn't work with. It appeared that BWSave
- was not saving some messages marked for saving, but in
- fact the messages were in the save packet; you just
- couldn't see them with the Blue Wave reader. As far as I
- can tell, using the 1.2 version of BWSave will 'correct'
- the broken save packet and all saved messages will show
- up automagically.
-
-
- New in version 1.3:
-
- Added '/all' switch to save _all_ messages in the source
- mail packet regardless of the Mark status.
-
- Added '/conf=' switch to save all messages from a
- specific conference.
-
- Added '/noinf' switch to suppress copying of the
- BBS_NAME.INF file from the source packet.
-
- Added '/unread' switch to change the 'Read' status of all
- messages moved to the destination packet.
-
- Fixed (finally, I hope) the bug that was producing what
- appeared to be duplicated messages if the destination
- packet had originally been created by a Blue Wave door.
-
- Changed sorting algorthms to what should be a faster one,
- especially on large destination packets.
-
- Added 'spinner' to the sort so that BWSave doesn't look
- like it's not doing anything while the messages are being
- put in the proper order.
-
- Added wild card expansion for the source packet name(s)
- and multiple source packet handling without recompressing
- the destination packet each time.
-
- Fixed some memory allocation leaks and cleaned up some
- memory use, allowing BWSave to handle more messages in
- the destination packet (now can handle up to 2360
- messages in the destination packet).
-
- Removed display of conference titles.
-
- Added conference area tag to display of message being
- saved.
-
- Added 'xx messages moved to archive packet.' to end of
- BWSave's execution.
-
-
- In The Works:
-
- Unlimited size destination packets. This will probably be
- somewhat slower than the current memory-based approach,
- so it may be an option rather than the default behavior.
-
- OS/2 native version of BWSave. The current BWSave was
- develloped and tested in a DOX box under OS/2, but a 32-
- bit 'native' version should be out this summer. A 32-bit
- DOS version may also be done at the same time.
-
- User-modifiable configuration file for the archiver
- command lines, default command line switches, and other
- information.
-
- Updating PKTSTATS.BW file directly so that the
- destination packet always displays correctly in the
- packet list window of Blue Wave.
-
- More command line options.
-
-
- For Those Who Are Interested: This software was written
- in the C language, using Microsoft's C compiler ver.
- 6.00, and compressed with Fabrice Bellard's Lzexe file
- compressor.
