# fox eclass
#
# This eclass allows building SLOT-able FOX Toolkit installations
# (x11-libs/fox: headers, libs, and docs), which are by design
# parallel-installable, while installing only one version of the utils
# (dev-util/reswrap) and apps (app-editors/adie, sci-calculators/calculator,
# x11-misc/pathfinder, and x11-misc/shutterbug).
#
# Version numbering follows the kernel-style odd-even minor version
# designation.  Even-number minor versions are API stable, which patch
# releases aimed mostly at the library; apps generally won't need to be
# bumped for a patch release.
#
# Odd-number versions are development branches with their own SLOT and
# are API unstable; changes are made to the apps, and likely need to be
# bumped together with the library.
#
# Here are sample [R]DEPENDs for the fox apps
# fox versions that do not use this eclass are blocked in INCOMPAT_DEP below
#	1.0: '=x11-libs/fox-1.0*'
#	1.2: '=x11-libs/fox-1.2*'
#	1.4: '=x11-libs/fox-1.4*'
#	1.5: '~x11-libs/fox-${PV}'
#	1.6: '=x11-libs/fox-${FOXVER}*'
#
# Some concepts borrowed from gst-plugins and gtk-sharp-component eclasses
