| This file exists such that the m4/ directory will be created when cloning the |
| git repository. |
| |
| The m4/ directory is not directly used by this project, but libtoolize |
| populates this directory with files, recommending that the directory be |
| included in the macro search path for aclocal. |
| |
| Because autoreconf runs aclocal before libtoolize, this directory will not |
| exist when autoreconf is run, triggering an error from aclocal. |
| |
| Creating this directory (and keeping this file in it as a placeholder) |
| prevents this error. |
