configuration management system.

Usage:
  $MYNAME create module

The create command will cause a new module, named module, to appear as a
top-level-directory in your working copy. This change will also be made to
the repositry at the same time.

appearing in the current host's recipe file. This command does not alter
the repository.

cat <<EOF
$MYNAME provides a command-line interface to Rescomp's server
configuration management system.

Usage:
  $MYNAME state

This command indicates whether the system is "dirty" or "clean."

A dirty system is one that has missed an automated "sync" operation in order
to preserve changes made by installation operations occuring between the
repository's export and the system's call to "sync."

Dirty systems may have out-of-date configuration files. Subsquent sync or
commit operations can bring the sytem up-to-date.

cat <<EOF
$MYNAME provides a command-line interface to Rescomp's server
configuration management system.

Usage:
  $MYNAME commit

The commit command causes your changes to take effect. This means that
first, your working copy of all of the modules in the current host's 
recipe will be committed to the repository. This happens after we've run
a $MYNAME update to prevent out-of-date conflicts. If there are any 
conflicts that require human intervention, the command will fail and exit 
non-zero. 

Once $MYNAME is satisfied that all of your changes have been propogated to
the repository, we will roll-out your working copy to the live filesystem.
Every module appearing in the host's recipe file will be rolled out IN THE
ORDER OF APPEARANCE.

management system.

Usage:
  $MYNAME mkdir directory 

This command will create a new version-controlled directory in your working
copy.  Parent directories do not have to exist; they will be created 
automagically. This command only affects your working copy. It does not commit 
the change.

EOF
;;
          ls )
cat<<EOF
$MYNAME provides a command-line interface to Rescomp's server configuration
management system.

Usage:
  $MYNAME ls [ file | directory ]

current working directory. If a file or directory is specified, it will list
that instead.

EOF
;;
    link | ln )
cat<<EOF
$MYNAME provides a command-line interface to Rescomp's server configuration
management system.

Usage:
  $MYNAME ( link | ln ) [-f] ( file | directory ) ( link_name | directory)

The ln subcommand creates a symlink within the repository.  The first
argument is the target of the link, which can be either a file or a
directory.  The second argument is either the name of a link or the
directory in which to create a link of the same name as the target.
The force command causes ln to ignore any files or links already
present when creating the link. 
EOF
;;
          lsattr )
cat<<EOF
$MYNAME provides a command-line interface to Rescomp's server configuration
management system.

Usage:
  $MYNAME lsattr [ file | directory ]

The lsattr subcommand lists out the confman attributes of files in the
repository. These attributes can be used to store information such as
file permissions, ownership, comment characters, syntax checkers, and
even commands to execute when changing the file.

EOF
;;
          chattr )
cat<<EOF
$MYNAME provides a command-line interface to Rescomp's server configuration
management system.

Usage:
  $MYNAME chattr attribute value [ file | directory ]

The chattr subcommand alters the confman attributes of files in the
repository. These attributes can be used to store information such as
file permissions, ownership, comment characters, syntax checkers, and
even commands to execute when changing the file.

EOF
;;
          rmattr )
cat<<EOF
$MYNAME provides a command-line interface to Rescomp's server configuration
management system.

Usage:
  $MYNAME rmattr attribute [ file | directory ]

The rmattr subcommand removes the confman attributes of files in the
repository. These attributes can be used to store information such as
file permissions, ownership, comment characters, syntax checkers, and
even commands to execute when changing the file.

cat <<EOF
$MYNAME provides a command-line interface to Rescomp's server configuration
management system.

Usage:
  $MYNAME chown [ -R ] owner [ file | directory ] 

The chown command works like it's unix equivalent. It does not support
user:group notation. The only option it will take is -R for recursive.

EOF
;;
          chg* )
cat <<EOF
$MYNAME provides a command-line interface to Rescomp's server configuration
management system.

Usage:
  $MYNAME chgrp group [ file | directory ]

cat <<EOF
$MYNAME provides a command-line interface to Rescomp's server configuration
management system.

Usage:
  $MYNAME chmod mode [ file | directory ] 

The chmod command works like it's unix equivalent. Note that it will only
accept octets as permissions -- it will not interpret symbolic permissions
correctly. The only option it will take is -R for recursive.

EOF
;;
          chc* )
cat <<EOF
$MYNAME provides a command-line interface to Rescomp's server configuration
management system.

Usage:
  $MYNAME chcom comment-character [ file | directory ] 

The chcom subcommand takes a file or directory as an argument and changes the
comment string associated with it. This will typically only be useful when
confman has guessed the comment character of your file incorrectly.

EOF
;;
    chl* )
cat <<EOF
$MYNAME provides a command-line interface to Rescomp's server configuration
management system.

Usage:
   $MYNAME chln target link_name

The chln subcommand takes a confman link as an argument and changes the
target on the live filesystem to which it points.  This works for
"simulated" symlinks to files on the live filesystem, not on actual
symlinks within your confman working copy.
EOF
;;
          checkl* )
cat <<EOF
$MYNAME provides a command-line interface to Rescomp's server

and gives you a listing of current checkpoints with some other cool info.
This command does not alter the repository.

EOF
;;
          checkn* )
cat <<EOF
$MYNAME provides a command-line interface to Rescomp's server
configuration management system.

Usage:
  $MYNAME checknew module name

The newcheck command creates a named checkpoint for the specified module.
This change is committed to the repository immediately.

EOF
;;
          checkc* )
cat <<EOF
$MYNAME provides a command-line interface to Rescomp's server
configuration management system.

Usage:
  $MYNAME checkclear module name

This change is committed to the repository immediately.

EOF
;;
          ro* )
cat <<EOF
$MYNAME provides a command-line interface to Rescomp's server
configuration management system.

Usage:
  $MYNAME rollback module [ checkpoint | YYYYMMDD [HHMM] ]

The rollback command first rolls your working copy of module back to the
named checkpoint. You can optionally roll-back to a specific point in time
using a date (and optionally time) as specified in the usage statement. 
This change is immediately committed to the repository.

After the rollback is complete, we perform the equivalent of a:
  $MYNAME commit
