=head1 NAME
FCM::System::CM
=head1 SYNOPSIS
use FCM::System::CM;
my $system = FCM::System::CM->new(\%attrib);
my ($out, $err) = $system->svn({}, @args);
=head1 DESCRIPTION
The FCM code management sub-system. This is currently a thin adaptor of
L<FCM1::Cm|FCM1::Cm>.
=head1 METHODS
=over 4
=item $class->new(\%attrib)
Returns a new instance. This class should normally be initialised by
L<FCM::System|FCM::System>.
=item $system->cm_branch_create(\%option,@args)
Implement the C<fcm branch-create> command. On success, return the branch name
created.
=item $system->cm_branch_list(\%option,@args)
Implement the C<fcm branch-list> command.
=item $system->cm_checkout(\%option,@args)
Thin wrapper of the C<svn checkout> command. Ensure checkout to clean location.
=item $system->cm_diff(\%option,@args)
Thin wrapper of the C<svn diff> command. Allow --graphical option.
=item $system->cm_loc_layout(\%option,@args)
Implement the C<fcm loc-layout> command.
=item $system->cm_project_create(\%option,@args)
Implement the C<fcm project-create> command.
=item $system->cm_branch_delete(\%option,@args)
=item $system->cm_branch_info(\%option,@args)
=item $system->cm_commit(\%option,@args)
=item $system->cm_check_missing(\%option,@args)
=item $system->cm_check_unknown(\%option,@args)
=item $system->cm_merge(\%option,@args)
=item $system->cm_mkpatch(\%option,@args)
=item $system->cm_resolve_conflicts(\%option,@args)
=item $system->cm_switch(\%option,@args)
=item $system->cm_update(\%option,@args)
Thin adaptors for the corresponding code management functions in
L<FCM1::Cm|FCM1::Cm>.
=item $system->svn($app,\%option,@args)
Invokes a system call to L<svn|svn> $app with @args. %option is not currently
used, but is left in the argument list for compatibility with the other methods.
