+# FLAC needs relatively recent versions of autotools for autogen.sh to
+# run properly. For example, if your autoconf is too old, it will not
+# check for inttypes.h and compilation will fail later. If you are
+# having problems with autogen.sh it is best to upgrade to at least the
+# following if possible:
+#
+# - autoconf 2.59
+# - automake 1.8.5
+# - libtool 1.5.6
+#
+# You may need to specify -I /SOME_PATH/share/aclocal if the packages
+# FLAC relies on (autotools, libogg, libiconv) are installed in
+# non-standard places.
+#
+# If you don't have XMMS installed at all, you should comment out
+# AM_PATH_XMMS in configure.in.
+#
+# 'hacks' is the place to put some commands you may need. There is one
+# that seems to be necessary in some situations:
+#
+# * FLAC uses iconv but not gettext. iconv requires config.rpath which
+# is supplied by gettext, which is copied in by gettextize. But we
+# can't run gettextize since we do not fulfill all it's requirements
+# (because we don't use it).
+#
+# If the default doesn't work, try:
+#
+#hacks="cp /usr/share/gettext/config.rpath ."
+#
+# Otherwise, this is the no-op:
+hacks=true
+#
+# Also watchout, if you replace ltmain.sh, there is a bug in some
+# versions of libtool (or maybe autoconf) on some platforms where the
+# configure-generated libtool does not have $SED defined. See also:
+#
+# http://lists.gnu.org/archive/html/libtool/2003-11/msg00131.html
