=head1 NAME
P4::Revision
=head1 SYNOPSIS
use P4;
$p4 = new P4;
$p4->Connect() or die( "Failed to connect to Perforce" );
for $file in ( $p4->RunFilelog( "//depot/some/file" ) )
{
for $rev in ( $file->Revisions() )
{
...
}
=head1 DESCRIPTION
P4::Revision objects represent revisions of files in a
Perforce repository. While users are free to create objects
of this class in their own scripts, their primary use is
that they are returned as part of the output of
C<P4::RunFilelog()>.
=head1 BUILT-IN METHODS

C<$rev = new P4::Revision( $depotFile );>
Constructs a new P4::Revision object for the specified file.

=item Integrations()
=over
C<$rev-E<gt>Integrations();>
Returns an array of P4::Integration objects representing
all the integration records for this revision.

=head1 OTHER METHODS
This module uses Perl's AutoLoader to implement methods
that get and set the attributes of a revision. So,
attributes such as the revision number, change number,
user, client etc. are available simply by calling a
method of the same name. A partial list of available
attributes is:
=over
C<< $rev->Rev() >> - The revision number
C<< $rev->Change() >> - The changelist number
C<< $rev->Type() >> - The Perforce filetype
C<< $rev->Time() >> - The timestamp
C<< $rev->User() >> - The submitting user
C<< $rev->Client() >> - The submitting client
C<< $rev->FileSize() >> - The size of the file
C<< $rev->Digest() >> - The MD5 digest
C<< $rev->Desc() >> - First 31 chars of description
=back
Whether or not a given attribute is available depends on
the way in which the object was constructed, and sometimes
on the version of the server. For example, servers older
than 2005.1 do not report the MD5 digest of revisions to
the client; in this case, the attribute will be
undefined.
