| 5 | ### mdw_LIBTOOL_VERSION_INFO | |
| 6 | ### | |
| 7 | ### DESCRIPTION | |
| 8 | ### | |
| 9 | ### Decodes the `PACKAGE_VERSION' variable as a `libtool' version-info | |
| 10 | ### string, available as the `@LIBTOOL_VERSION_INFO@' substitution. | |
| 11 | ### Strictly speaking, this is very naughty. | |
