72: lonpublisher - LON-CAPA publishing handler
73:
74: =head1 Synopsis
75:
76: lonpublisher takes the proper steps to add resources to the LON-CAPA
77: digital library. This includes updating the metadata table in the
78: LON-CAPA database.
79:
80: =head1 Description
81:
82: lonpublisher is many things to many people.
83: To all people it is woefully documented.
84: This documentation conforms to this standard.
85:
86: This module publishes a file. This involves gathering metadata,
87: versioning the file, copying file from construction space to
88: publication space, and copying metadata from construction space
89: to publication space.
