+# pbuilder hook script: choose optional compiler rather than default one
+#  
+# Sometimes we want to choose other compiler than default, because of improving
+# code to conform to standard, check compiler quality or so. This script will
+# ease it. Try enable hook script and set "CHOOSE_COMPILER" variables as clang,
+# gcc-*, or other compilers (note: however, now only clang and gcc can works
+# well and others fails to build).
+#
+# i.e.)
+#  $ sudo CHOOSE_COMPILER="clang" pbuilder --build foobar_1.0-1.dsc
+#  $ sudo CHOOSE_COMPILER="gcc-4.6" pbuilder --build foobar_1.0-1.dsc
