| realpath is a simple implementation of the realpath utility: |
| http://www.gnu.org/software/coreutils/manual/html_node/realpath-invocation.html |
| since Mac OS X does not have anything equivalent. |
| |
| This version takes no options. |
| |
| This is based on the default GNU/Linux implementation that allows the last |
| component to not exist. This is different than the Debian implementation that |
| requires the last component to exist. Supporting the GNU/Linux implementation |
| makes writing scripts that depend on realpath much easier, and is probably |
| closer to what Apple may actually ship as a realpath implementation in the |
| future. |
| |
| realpath only builds/runs on Darwin. |
