+=head1 NAME
+
+PathData/ComponentBased.pm - Provides the location of archived releases with an old-style archive arrangement.
+
+=head1 DESCRIPTION
+
+Parses a file containing paths to component release packets on both the local and remote archives.
+
+=head1 INTERFACE
+
+=head2 ProcessLine
+
+This interprets an C<archive_path_file> line from your F<reltools.ini>, and goes away to parse the F<archive_path.txt> file (which it does using the internal method C<ParsePathData>).
+
+The parser expects each line in the file to have the following form: 
+ 
+ <component_name>  <local_archive_path>  <remote_archive_path>
+
+So an example file might have the following structure:
+
+ #
+ # App Engines
+ #
+ agnmodel     X:\ProjectX\appeng      \ProjectX\appeng
+ cntmodel     X:\ProjectX\appeng      \ProjectX\appeng
+ damodel      X:\ProjectX\appeng      \ProjectX\appeng
+ ...
+ ...
+ #
+ # App Framework
+ #
+ apparc       X:\ProjectX\appframework      \ProjectX\appframework
+ eikstd       X:\ProjectX\appframework      \ProjectX\appframework
+ etext        X:\ProjectX\appframework      \ProjectX\appframework
+ ...
+ ...
+ #
+ # Default path
+ #
+ default      X:\ProjectX\misc       \ProjectX\misc
+
+The C<default> line is optional (and there should be only one in the file). The C<default> value is the path given to all component releases which are not explicity listed in the file.
+
+[Note: text following a # is treated as a comment]   
+
+=head2 Methods that return paths
+
+All of these methods are expected to return the full location where the files should be stored; i.e. local archive paths should end in "\component\version" and remote archive paths should end in "/component".
+
+=head2 LocalArchivePathForNewComponent
+
+This takes a component and a version and (optionally) the name of the project to store the component in.
+
+=head2 LocalArchivePathForExistingComponent
+
+This takes a component and a version.
+
+=head2 LocalArchivePathForImportingComponent
+
+This takes a component, a version, and the remote path where the component was found.
+
+=head2 RemoteArchivePathForExistingComponent
+
+This takes a component and a version.
+
+=head2 RemoteArchivePathForExportingComponent
+
+This takes a component, a version, and the local path where the component was found.
+
+=head2 ListComponents
+
+This may take "1" to indicate that it should list the components stored remotely, not locally. 
+
+=head2 ListVersions
+
+This takes a component. It may optionally take a "1" to indicate that it should list the versions stored remotely, not locally.
+
+=head2 ListProjects
+
+=head2 ComponentProjects
+
+=head2 ComponentProject
+
+These methods all throw an error, since projects aren't a relevant concept in this type of archive structure.
+
+=head1 IMPLEMENTATION
+
+=head2 LocalArchivePath
+
+Takes a component name. Returns the path of the component release packet on the local archive. Dies if not found.
+
+=head2 RemoteArchivePath
+
+Takes a component name. Returns the path of the component release packet on the remote archive (either an FTP site or a network drive). Dies if not found.
+
+=head1 KNOWN BUGS
+
+None.
