56 | Install emacs quickly | |
57 | ||
58 | -n, --dry-run print installation commands instead of | |
59 | executing them | |
60 | ||
61 | -f, --force install even files that haven't changed | |
62 | -v, --verbose print messages describing what is done | |
63 | ||
64 | -p, --prune prune old generated files | |
65 | -P, --no-prune don't prune old generated files (default) | |
66 | --prune-only prune old generated files, but don't install | |
67 | ||
68 | --help display this help and exit | |
69 | --version output version information and exit | |
70 | ||
71 | $me install emacs \`incrementally,' that is, it will | |
72 | install only those files that have changed since the last time it was | |
73 | invoked, and remove any obsolete files from the installation | |
74 | directories. It also uses hard-links into the source and build trees to | |
75 | do the install, so it uses much less space than the default Makefile | |
76 | install target; however, this also means that $me can | |
77 | not install onto a disk partition other than the one on which the source | |
78 | and build directories reside. | |
79 | ||
80 | Optionally, $me can also remove old versions of | |
81 | automatically generated files that are version-specific (such as the | |
82 | versioned emacs executables in the \`src' directory, and the DOC-* files | |
83 | in the \`etc' directory). The latter action is called \`pruning,' and | |
84 | can be enabled using the \`-p' or \`--prune' options. | |
