Redmine/extra/svn/reposman.rb

#!/usr/bin/ruby

# == Synopsis
#
# reposman: manages your svn repositories with Redmine
#
# == Usage
#
#     reposman [ -h | --help ] [ -v | --verbose ] [ -V | --version ] [ -q | --quiet ] -s /var/svn -r redmine.host.org
#     example: reposman --svn-dir=/var/svn --redmine-host=redmine.mydomain.foo
#              reposman -s /var/svn -r redmine.mydomain.foo
#
# == Arguments (mandatory)
# 
# -s, --svn-dir=DIR
#    use DIR as base directory for svn repositories
#
# -r, --redmine-host=HOST
#    assume Redmine is hosted on HOST.
#    you can use :
#    * -r redmine.mydomain.foo        (will add http://)
#    * -r http://redmine.mydomain.foo
#    * -r https://mydomain.foo/redmine
#
# == Options
#
# -o, --owner=OWNER
#    owner of the repository. using the rails login allow user to browse
#    the repository in Redmine even for private project
#
# -u, --url=URL
#    the base url Redmine will use to access your repositories. This
#    will be used to register the repository in Redmine so that user
#    doesn't need to do anything. reposman will add the identifier to this url :
#
#    -u https://my.svn.server/my/reposity/root # if the repository can be access by http
#    -u file:///var/svn/                       # if the repository is local
#    if this option isn't set, reposman won't register the repository
#
# -t, --test
#    only show what should be done
#
# -h, --help:
#    show help and exit
#
# -v, --verbose
#    verbose
#
# -V, --version
#    print version and exit
#
# -q, --quiet
#    no log
#
