24 # @DESCRIPTION:
25 # In case your Qt4 application provides various translations, use this variable
26 # to specify them in order to populate "linguas_*" IUSE automatically. Make sure
27 # that you set this variable before inheriting qt4-r2 eclass.
28 # Example:
29 # @CODE
30 # LANGS="en el de"
31 # @CODE
32 for x in ${LANGS}; do
33 IUSE+=" linguas_${x}"
34 done

36 # @ECLASS-VARIABLE: LANGSLONG
37 # @DEFAULT_UNSET
38 # @DESCRIPTION:
39 # Same as above, but this variable is for LINGUAS that must be in long format.
40 # Remember to set this variable before inheriting qt4-r2 eclass.
41 # Look at ${PORTDIR}/profiles/desc/linguas.desc for details.

172 # that it exists. Otherwise eqmake4 fails.
173 #
174 # All other arguments are appended unmodified to qmake command line. For
175 # recursive build systems, i.e. those based on the subdirs template, you
176 # should run eqmake4 on the top-level project file only, unless you have
177 # strong reasons to do things differently. During the building, qmake
