comparison build-aux/install-sh @ 317:aab761616489 default tip
Rearrange some Autoconf files.
Autoconf was failing to detect install-sh at the top level and needed
some explicit directions. It also wants config.guess and config.sub to
be provided too.
A few other macros have also been updated.

100 In the 4th, create DIRECTORIES. | |

102 Options: | |

104 --version display version info and exit. | |
105 | |
106 -c (ignored) | |
107 -C install only if different (preserve data modification time) | |
108 -d create directories instead of installing files. | |

111 -o USER $chownprog installed files to USER. | |
112 -p pass -p to $cpprog. | |
113 -s $stripprog installed files. | |
114 -S SUFFIX attempt to back up existing files, with suffix SUFFIX. | |
115 -t DIRECTORY install into DIRECTORY. | |
116 -T report an error if DSTFILE is a directory. | |

122 By default, rm is invoked with -f; when overridden with RMPROG, | |
123 it's up to you to specify -f if you want it. | |
124 | |
125 If -S is not specified, no backups are attempted. | |
