Deprecated develoment branch.

#!/usr/bin/env ruby

# == Synopsis
#
# reposman: manages your repositories with Redmine
#
# == Usage
#
#    reposman [OPTIONS...] -s [DIR] -r [HOST]
#
#  Examples:
#    reposman --svn-dir=/var/svn --redmine-host=redmine.example.net --scm subversion
#    reposman -s /var/git -r redmine.example.net -u http://svn.example.net --scm git
#
# == Arguments (mandatory)
#
#   -s, --svn-dir=DIR         use DIR as base directory for svn repositories
#   -r, --redmine-host=HOST   assume Redmine is hosted on HOST. Examples:
#                             -r redmine.example.net
#                             -r http://redmine.example.net
#                             -r https://example.net/redmine
#   -k, --key=KEY             use KEY as the Redmine API key
#
# == Options
#
#   -o, --owner=OWNER         owner of the repository. using the rails login
#                             allow user to browse the repository within
#                             Redmine even for private project. If you want to
#                             share repositories through Redmine.pm, you need
#                             to use the apache owner.
#   -g, --group=GROUP         group of the repository. (default: root)
#   --scm=SCM                 the kind of SCM repository you want to create (and
#                             register) in Redmine (default: Subversion).
#                             reposman is able to create Git and Subversion
#                             repositories. For all other kind, you must specify
#                             a --command option
#   -u, --url=URL             the base url Redmine will use to access your
#                             repositories. This option is used to automatically
#                             register the repositories in Redmine. The project
#                             identifier will be appended to this url. Examples:
#                             -u https://example.net/svn
#                             -u file:///var/svn/
#                             if this option isn't set, reposman won't register
#                             the repositories in Redmine
#   -c, --command=COMMAND     use this command instead of "svnadmin create" to
#                             create a repository. This option can be used to
#                             create repositories other than subversion and git
#                             kind.
#                             This command override the default creation for git
#                             and subversion.
#   --http-user=USER          User for HTTP Basic authentication with Redmine WS
#   --http-pass=PASSWORD      Password for Basic authentication with Redmine WS
#   -f, --force               force repository creation even if the project
#                             repository is already declared in Redmine
#   -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
