Subj: 	rcs history information...

Anyone got any better methods for obtaining the history information
for files that are being worked on in a sandbox!  Ideally I would like
to get to the point of just having to enter the descriptive information
in the rcs-history header only once.  And tweek my srequest to take that
information and supply it in the srequest form for me... 8^)

Here's my first stab at the script to get history information, I not
too pleased with it but it's a starting point...

If there's a better mail alias or other users who may be able to provide
feed-back please let me know.

ps.
	I think the file is all here, so if you want to give it a try
(I use lots of ksh functions so I might of missed one or two).

#!/usr/bin/ksh -p

# information for all the files in the set.

Subj: 	Re: rcs history information...
Mike, this is from lastin: 	/usr/sde/ode1.5/man/man1/bci.1 -- this information

is really internal to the workings of bci, and so it was removed from the
ode man page for version 2.0.  You may be able to use this to pull the rcs
history from the file in some way...	-josh

  -xlog rev[,rev...]
       Obtains log messages for file by extracting all RCS-style log messages
       from the comma-separated list of revisions.

  -xblog
       Obtains log messages for file by extracting RCS-style log messages
       from all revisions of file in this branch.

....

  If the -xlog option has been specified, an attempt is made to obtain the
  log message from file by extracting all RCS-style log messages from the
  comma-separated list of branches, beginning after a $Log...$ line, and con-
  tinuing up to but not including the first line that does not begin with the
  precise RCS comment leader recorded for the file. Note: be careful with
  white space variants when manually editing such areas - most leaders end
  with a space and the text typically begins with a tab. The comment leader
  portion of each extracted line is stripped off along with any initial tab
  character.  The revision number, date/time, and author revision banner is
  compressed into a date/time and author stamp, which is appended to the end
  of each extracted revision message.

Subj: 	Re: rcs history information...

Not sure how useful these flags are... the -xlog and -xblog (if used)
will create the check in log message,  not provide me with the current
log information for a checked in file.
