| 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. |
