- \fIbbc\fR is a BBoard
- reading/checking program that interfaces to the BBoard
- channel.
-
- The \fIbbc\fR program has three action switches which direct its operation:
-
- The `\-read' switch invokes the \fImsh\fR program on the named
- \fIBBoards\fR. If you also specify
- the `\-archive' switch, then \fIbbc\fR will invoke the \fImsh\fR program on
- the archives of the named \fIBBoards\fR. If no \fIBBoards\fR are given
- on the command line, and you specified `\-archive',
- \fIbbc\fR will not read your `bboards' profile entry, but will
- read the archives of the \*(lqsystem\*(rq \fIBBoard\fR instead.
-
- The `\-check' switch types out status information for the named \fIBBoards\fR.
- \fIbbc\fR
- can print one of several messages depending on the status of both the
- BBoard
- and the user's reading habits.
- As with each of these messages, the number
- given is the item number of the last item placed in the
- BBoard.
- This number (which is marked in the messages as the \*(lqBBoard\-Id\*(rq) is
- ever increasing. Hence, when \fIbbc\fR
- says \*(lqn items\*(rq, it really means that the highest BBoard\-Id is \*(lqn\*(rq.
- There may, or may not actually be \*(lqn\*(rq items in the BBoard.
- Some common messages are:
- .in +1i
-
- .ti -.5i
- \fBBBoard \-\- n items unseen\fR
- .br
- This message tells how many items the user has not yet seen.
- When invoked with the `\-quiet' switch,
- this is the only informative line that \fIbbc\fR will possibly print out.
-
- .ti -.5i
- \fBBBoard \-\- empty\fR
- .br
- The BBoard is empty.
-
- .ti -.5i
- \fBBBoard \-\- n items (none seen)\fR
- .br
- The BBoard has items in it, but the user hasn't seen any.
-
- .ti -.5i
- \fBBBoard \-\- n items (all seen)\fR
- .br
- The BBoard is non\-empty, and the user has seen everything in it.
-
- .ti -.5i
- \fBBBoard \-\- n items seen out of m\fR
- .br
- The BBoard has at most m\-n items that the user has not seen.
- .in -1i
-
- The `\-topics' switch directs \fIbbc\fR to print three items about the named
- \fIBBoards\fR:
- it's official name,
- the number of items present,
- and the date and time of the last update.
- If no \fIBBoards\fR
- are named, then all BBoards
- are listed. If the `\-verbose' switch is given, more information is output.
-
- The `\-quiet' switch specifies that \fIbbc\fR should be silent if no
- \fIBBoards\fR are found with new information.
- The `\-verbose' switch specifies that \fIbbc\fR is to consider you to be
- interested in \fIBBoards\fR that you've already seen everything in.
-
- To override the default \fImshproc\fR and the profile entry,
- use the `\-mshproc\ program' switch.
- Any arguments not understood by \fIbbc\fR are passed to this program.
- The `\-protocol' switch tells \fIbbc\fR that your \fImshproc\fR knows about
- the special \fIbbc\fR protocol for reporting back information.
- \fImsh\fR\0(1), the default \fImshproc\fR, knows all about this.
-
- The `\-file\ BBoardsfile' switch tells \fIbbc\fR to use a non\-standard
- \fIBBoards\fR file when performing its calculations.
- Similarly, the `\-user BBoardsuser' switch tells \fIbbc\fR to use a
- non\-standard username.
- Both of these switches are useful for debugging a new \fIBBoards\fR or
- \fIPOP\fR file.
-
- The `\-rcfile\ rcfile' switch overrides the use of \fI\&.bbrc\fR for
- user\-specific BBoards information.
- If the value given to the switch is not absolute,
- (i.e., does not begin with a \fB/\fR\0),
- it will be presumed to start from the current working directory.
- If this switch is not given (or the `\-norcfile' switch is given),
- then \fIbbc\fR consults the environment variable \fB$MHBBRC\fR,
- and honors it similarly.
- If this environment variable is not set,
- then the file \fI\&.bbrc\fR in the user's \fB$HOME\fR directory is used.
