NAME
       cvsutils	- CVS utilities	for use	in working directories

SYNOPSIS
       cvsu [options]
       cvsco  [	options	]
       cvsdiscard  [ options ]
       cvspurge	 [ options ]
       cvstrim	[ options ]
       cvschroot  [ options ]
       cvsdo  [	options	]

DESCRIPTION
       The  idea  of  cvsutils	is to facilitate working with the files	in the
       working directory of a developer	using CVS  (Concurrent	Versions  Sys-
       tem).

       From  the  point	 of  view  of CVS, working directories have low	value,
       since they can easily be	recreated  using  the  cvs  checkout  command.
       Also  the  cvs  update  command will show the status of the files, i.e.
       whether they have been modified,	added or removed.

       CVS in it's current state is a client-server system that	does  most  of
       its  work  on the server	side. CVS provides only	few (if	any) means for
       managing	the working directory without communicating with the server.

       There are, however, several reasons why such means are necessary:

       *      There is enough information on the client	side  to  create  fast
	      tools for	sorting	and purging the	working	directory without con-
	      tacting the CVS server.

       *      Checking out a big module	over a slow line  can  take  too  much
	      time.

       *      There should be support for disconnected operations.

       *      CVS  poses  certain unnecessary restrictions on read-only	users,
	      e.g.  cvs	add command doesn't work for them.

CVSU
       cvsu is "cvs update offline". It	lists the files	found in  the  current
       directory (or in	the directories	which you specify). Following is taken
       into account:

       *      Attributes of the	file.

       *      Information about	the file in CVS/Entries.

       *      Timestamp	of the	file  compared	to  the	 timestamp  stored  in
	      CVS/Entries.

       Run  cvsu --help	to see supported command line options. The options can
       be abbreviated.	This functionality is provided by Perl,	and  can  vary
       from one	machine	to another.

CVSCO
       cvsco is	a "cruel checkout". In other words, it removes results of com-
       pilation	and discards local changes. It deletes all  the	 files	except
       listed  unmodified  ones	 and  checks  out everything which seems to be
       missing.	 Please	note, that cvsco doesn't update	 files	which  haven't
       been modified locally. It only reloads missing files and	files which it
       erases.

CVSDISCARD
       cvsdiscard is "discard my changes". In other words, it  discards	 local
       changes	but  keeps results of compilation. It works like cvsco,	but it
       only deletes files which	are likely to cause merge conflicts.

CVSPURGE
       cvspurge	leaves all files known to CVS, but removes the	rest.	Unlike
       cvsco,  it  doesn't  remove  local changes.  It is useful to test local
       changes in the otherwise	clean source tree.

CVSTRIM
       cvstrim removes files and directories unknown to	CVS. Files  listed  in
       .cvsignore  are	not  removed. The idea is to remove the	files that are
       not resulted from the normal build process -  backups,  coredumps  etc.
       cvstrim relies on .cvsignore files being	correct. Note that the backups
       for modified files are removed.

CVSCHROOT
       cvschroot makes it possible to change CVS/Root in all subdirectories to
       the  given  value. Currently the	only argument accepted is the new CVS-
       ROOT value.  Old-style CVS/Repository files that	contain	the full  path
       to  the	repository  are	 updated  to  reflect  the  change.  New-style
       CVS/Repository don't need to be changed.	If  the	 environment  variable
       CVSROOT	is  defined,  it  overrides the	contents of CVS/Root. In other
       words, it is treated as the old CVS root.

CVSDO
       cvsdo simulates some of the CVS commands	 (currently  add,  remove  and
       diff)  without  any access to the CVS server. Using cvsdo add and cvsdo
       remove allows you to create diffs with cvs diff -N, and all removed and
       added  files  will appear in the	diff correctly,	as if you had used cvs
       add and cvs remove respectively.

       cvsdo diff tries	to locate the backup copies of the modified files.  If
       they  can  be  found,  they are compared	with the current version using
       diff.  Only those backup	copies are used	 that  have  the  modification
       date equal the date listed in CVS/Entries for the modified file.	 cvsdo
       diff patches the	diff output to make it more robust to apply. An	excep-
       tion  is	 made  for files named "ChangeLog" - in	this case diff will be
       instructed to omit all context lines, so	that the patch can be  applied
       even  if	 other	changes	 have  been written to the ChangeLog. Also the
       added files are handled properly. The header  of	 the  diff  output  is
       patched in such way that	at least GNU patch will	create a new file when
       the resulting patch is applied and remove that file when	the  patch  is
       reverted.
