| 24 | # be useful to your project, you should place a copy of it under |
| 25 | # version control in the top-level directory of your project. The |
| 26 | # intent is that all customization can be done with a bootstrap.conf |
| 27 | # file also maintained in your version control; gnulib comes with a |
| 28 | # template build-aux/bootstrap.conf to get you started. |

| 50 | Bootstrap this package from the checked-out sources. |
| 51 | |
| 52 | Options: |
| 53 | --gnulib-srcdir=DIRNAME specify the local directory where gnulib |
| 54 | sources reside. Use this if you already |
| 55 | have gnulib sources on your machine, and |
| 56 | do not want to waste your bandwidth downloading |
| 57 | them again. Defaults to \$GNULIB_SRCDIR |
| 58 | --bootstrap-sync if this bootstrap script is not identical to |
| 59 | the version in the local gnulib sources, |
| 60 | update this script, and then restart it with |
| 61 | /bin/sh or the shell \$CONFIG_SHELL |
| 62 | --no-bootstrap-sync do not check whether bootstrap is out of sync |
| 63 | --copy copy files instead of creating symbolic links |
| 64 | --force attempt to bootstrap even if the sources seem |
| 65 | not to have been checked out |
| 66 | --no-git do not use git to update gnulib. Requires that |
| 67 | --gnulib-srcdir point to a correct gnulib snapshot |
| 68 | --skip-po do not download po files |
| 69 | |
| 70 | If the file $me.conf exists in the same directory as this script, its |
| 71 | contents are read as shell variables to configure the bootstrap. |
| 72 | |
| 73 | For build prerequisites, environment variables like \$AUTOCONF and \$AMTAR |
| 74 | are honored. |
| 75 | |
| 76 | Running without arguments will suffice in most cases. |
