Hi,
This is an eclass that provides functionality needed to further split
poppler into its constituent libraries and utilities. The current way
of doing this, where we have poppler with utils in app-text/poppler and
the bindings for qt3, qt4 and glib in app-text/poppler-bindings is
suboptimal.
1) it requires us to either enable by default a useflag that will pull
in a major toolkit or die when all use-flags are unset.
2) The cairo use-flag is a subset of the gtk use-flag (which is in
itself misnamed) and thus enabling [cairo] will enable [gtk] but
without this being reflected in the metadata.
Also, as part of the restructuring, I will be able to move packages
around a bit so the libs are put in dev-libs/poppler{,-glib,-qt3,-qt4}
and the utils are put in app-text/poppler-utils.
Without further ado, the eclass:

# @USAGE: GROUP [package1] [package2]
# @DESCRIPTION:
# Will export the appropriate variables to override PKG_CHECK_MODULES autoconf
# macros, with the string by default. If packages are specified, they will
# be looked up with pkg-config and the appropriate LIBS and CFLAGS substituted.
# LIBS and CFLAGS can also be specified per-package with the following syntax:
# @CODE
# package=LIBS%CFLAGS
# @CODE
# = and % have no effect unless both are specified.
# Here is an example:
# @CODE
# pkg_check_modules_override GASH gtk+-2.0=-jule% gobject-2.0
# @CODE
# The above example will do:
# export GASH_CFLAGS+= -jule
# export GASH_LIBS+=
# export GASH_CFLAGS+= $(pkg-config --cflags gobject-2.0)
# export GASH_LIBS+= $(pkg-config --libs gobject-2.0)
#
# NOTE: If a package is not found, the string will be inserted in place of
# GROUP_CFLAGS and GROUP_LIBS
