1 This directory is where .m4 files providing third-party autoconf
2 macros can be placed to be automatically found by the aclocal(1)
5 The .m4 files placed here could be shared among different versions
6 of aclocal, so be careful.
8 Even if no actual .m4 files are present, this directory is required
9 in order for aclocal to work properly. Please do not remove it.
