root/main/trunk/greenstone2/perllib/inexport.pm @ 32615

Revision 32615, 48.5 KB (checked in by kjdon, 20 months ago)

mods for incremental build. now we load in the reverse info db (archiveinf-src) and make changes to that, then write it out again at the end. did a bit of work to get html + supporting images working a bit better. for the cases where the main file is modified, or if the images are modified, or if links to those images are changed.
