+=head1 NAME
+
+PushPullRel.pm - class for moving releases between two local archives
+
+=head1 DESCRIPTION
+
+Provides an API to transfer releases between two local archives. (That is, non-encrypted archives,
+accessible as standard disk drives from the PC). Used by C<pushenv>, C<pullenv>, C<pushrel>,
+C<pullrel>.
+
+=head1 INTERFACE
+
+=head2 new
+
+Creates a new object of this class. Takes five parameters. 1) An IniData object corresponding
+to your local repository. 2) A foreign IniData object (or just a filename) describing the 
+remote repository. 3) A boolean, saying whether you're pushing to the remote site. If false,
+assumes you're pulling from the remote site. 4) Verbose. 5) Force (overwrites).
+
+=head2 TransferRel
+
+Takes a component name and version. Transfers that component.
+
+=head2 TransferEnv
+   
+Takes a component name and version. Transfers the environment of that component.
+
+=head2 PerformCopying
+
+Takes a component name, version, to release and from release directory. Performs initial checks on the release directories passed and then calls _DoCopying.
+
+=head2 Errors
+
+Returns an arrayref of all the errors encountered during TransferEnv.
+
+=head2 SummariseErrors
+
+Optional input copyRel flag which indicates whether to this summary is for a copyrel or not. Prints all the errors encountered.
+
+=head1 KNOWN BUGS
+
+None.
