-------------------------+--------------------------------
 Regenerating aclocal.m4 with `aclocal` is a standard part of an autotools
 workflow. `Automake` tells you to do it, `libtoolize` tells you to do it,
 `gettextize` tells you to do it, and I'm sure there are other tools that
 tell you to do it, too, that I'm just not thinking of now. However, the
 aclocal.m4 file in base contains some hard-coded macros in it, meaning
 that if you run `aclocal`, you're going to overwrite them and then be
 missing some of the macros you need. This is pretty simple to fix: you
 could rename the current aclocal.m4 file to acinclude.m4, or move it into
 the `m4/` directory in base, or both. After doing that, you can regenerate
 the aclocal.m4 file with `aclocal -I m4`.
