Once you have used CVS to store a version control
history--what files have changed when, how, and by
whom, there are a variety of mechanisms for looking
through the history.
Whenever you commit a file you specify a log message.
To look through the log messages which have been
specified for every revision which has been committed,
use the cvs log command (see section log--Print out log information for files).
You can use the history file (see section The history file) to
log various CVS actions. To retrieve the
information from the history file, use the cvs
history command (see section history--Show status of files and users).
Note: you can control what is logged to this file by using the
`LogHistory' keyword in the `CVSROOT/config' file
(see section The CVSROOT/config configuration file).
You can customize CVS to log various kinds of
actions, in whatever manner you choose. These
mechanisms operate by executing a script at various
times. The script might append a message to a file
listing the information and the programmer who created
it, or send mail to a group of developers, or, perhaps,
post a message to a particular newsgroup. To log
commits, use the `loginfo' file (see section Loginfo).
To log tags, use the `taginfo' file (see section Taginfo).
To log commits, checkouts, exports, and tags,
respectively, you can also use the `-i',
`-o', `-e', and `-t' options in the
modules file. For a more flexible way of giving
notifications to various users, which requires less in
the way of keeping centralized scripts up to date, use
the cvs watch add command (see section Telling CVS to notify you); this command is useful even if you are not
using cvs watch on.
