It +;; accomodates the needs of applications making use of glib or gtk+ (with "or" +;; to be interpreted in the mathematical sense). This is achieved by adding +;; two phases run after the 'install' phase: +;; +;; 'glib-or-gtk-wrap' phase: +;; +;; a) This phase looks for GSettings schemas by verifying the existence of +;; path "datadir/glib-2.0/schemas" in all input packages. If the path is +;; found in any package, then all programs in "out/bin" are wrapped in scripts +;; where the environment variable "XDG_DATA_DIRS" is set and points to the +;; list of found schemas directories. +;; +;; b) Looks for the existence of "libdir/gtk-3.0" directories in all input +;; packages. If any is found, then the environment variable "GTK_PATH" is +;; suitably set and added to the wrappers. The variable "GTK_PATH" has been +;; preferred over "GTK_EXE_PREFIX" because the latter can only point to a +;; single directory, while we may need to point to several ones. +;; +;; 'glib-or-gtk-compile-schemas' phase: +;; +;; Looks for the presence of "out/share/glib-2.0/schemas".
