/* gap_frontends_main.c
* 1999.11.20 hof (Wolfgang Hofer)
*
* GAP ... Gimp Animation Package
*
* This Module contains:
* - MAIN of GAP_Plugins that are frontends to external programs
* those external programs are not available for all
* operating systems.
*
* - query registration of GAP Procedures (Video Menu) in the PDB
* - run invoke the selected GAP procedure by its PDB name
*
*
* GAP provides Animation Functions for the gimp,
* working on a series of Images stored on disk in gimps .xcf Format.
*
* Frames are Images with naming convention like this:
* Imagename_<number>.<ext>
* Example: snoopy_0001.xcf, snoopy_0002.xcf, snoopy_0003.xcf
*
* if gzip is installed on your system you may optional
* use gziped xcf frames with extensions ".xcfgz"
*
