+# Usage: $0 [-a arch] default_arch keyword fcdistro pldistro pkgs-file[..s]
+# default_arch is $pl_DISTRO_ARCH, but can be overridden

+
+#################### original language was (in this example, keyword=package)
+## to add to all distros
+# package: p1 p2
+## to add in one distro
+# package+f12: p1 p2
+## to remove in one distro
+# package-f10: p1 p2
+#################### replacement language
+## add in distro f10
+# +package=f10: p1 p2
+# or simply
+# package=f10: p1 p2
+## add in fedora distros starting with f10
+# +package>=f10: p1 p2
+# or simply
+# package>=f10: p1 p2
+## ditto but remove instead
+# -package=centos5: p1 p2
+# -package<=centos5: p1 p2
