Changeset 16385 for greenstone3

Timestamp:

2008-07-14T14:41:00+12:00 (16 years ago)

Author:

Message:

Processes new fedorahome and fedoraversion variables if these have been set in the gsdlsite.cfg files. Otherwise, if FEDORA_HOME env var has been set, it uses this to set either FEDORA2_HOME or FEDORA3_HOME as is needed by the Fedora import and build scripts. Additional minor (cosmetic) changes.
