| 96 | |
| 97 | $me install emacs \`incrementally,' that is, it will |
| 98 | install only those files that have changed since the last time it was |
| 99 | invoked, and remove any obsolete files from the installation |
| 100 | directories. It also uses hard-links into the source and build trees to |
| 101 | do the install, so it uses much less space than the default Makefile |
| 102 | install target; however, this also means that $me can |
| 103 | not install onto a disk partition other than the one on which the source |
| 104 | and build directories reside. |
| 105 | |
| 106 | Optionally, $me can also remove old versions of |
| 107 | automatically generated files that are version-specific (such as the |
| 108 | versioned emacs executables in the \`src' directory). |
| 109 | The latter action is called \`pruning,' and |
| 110 | can be enabled using the \`-p' or \`--prune' options. |
