# == Synopsis
#
# Reads an email from standard input and forward it to a Redmine server
# through a HTTP request.
#
# == Usage
#
# rdm-mailhandler [options] --url=<Redmine URL> --key=<API key>
#
# == Arguments
#
# -u, --url URL of the Redmine server
# -k, --key Redmine API key
#
# General options:
# --unknown-user=ACTION how to handle emails from an unknown user
# ACTION can be one of the following values:
# ignore: email is ignored (default)
# accept: accept as anonymous user
# create: create a user account
# -h, --help show this help
# -v, --verbose show extra information
# -V, --version show version information and exit
#
# Issue attributes control options:
# -p, --project=PROJECT identifier of the target project
# -s, --status=STATUS name of the target status
# -t, --tracker=TRACKER name of the target tracker
# --category=CATEGORY name of the target category
# --priority=PRIORITY name of the target priority
# -o, --allow-override=ATTRS allow email content to override attributes
# specified by previous options
# ATTRS is a comma separated list of attributes
#
# == Examples
# No project specified. Emails MUST contain the 'Project' keyword:
#
# rdm-mailhandler --url http://redmine.domain.foo --key secret
#
# Fixed project and default tracker specified, but emails can override
# both tracker and priority attributes using keywords:
#
# rdm-mailhandler --url https://domain.foo/redmine --key secret \\
# --project foo \\
# --tracker bug \\
# --allow-override tracker,priority
