AC_INIT([famas], [0.0.12], [andreas.wilm@gmail.com])

# The AC_INIT macro can take any source file as an argument. It just
# checks that the file is there, which should, in turn, mean that the
# source directory is there. AC_INIT generates the following m4
# macros, output variables and preprocessor symbols:
AC_SUBST(PACKAGE_NAME)
AC_SUBST(PACKAGE_TARNAME)
AC_SUBST(PACKAGE_VERSION)
AC_SUBST(PACKAGE_STRING)
AC_SUBST(PACKAGE_BUGREPORT)
