| 41 Options: | |
| 42 --gnulib-srcdir=DIRNAME Specify the local directory where gnulib | |
| 43 sources reside. Use this if you already | |
| 44 have gnulib sources on your machine, and | |
| 45 do not want to waste your bandwidth downloading | |
| 46 them again. | |
| 47 --copy Copy files instead of creating symbolic links. | |
| 48 --force Attempt to bootstrap even if the sources seem | |
| 49 not to have been checked out. | |
| 50 --skip-po Do not download po files. | |
| 51 | |
| 52 If the file $0.conf exists in the same directory as this script, its | |
| 53 contents are read as shell variables to configure the bootstrap. | |
| 54 | |
| 55 For build prerequisites, environment variables like \$AUTOCONF and \$AMTAR | |
| 56 are honored. | |
| 57 | |
| 58 Running without arguments will suffice in most cases. | |
