+# through a HTTP request.

+#
+# == Arguments
+# 
+#   -u, --url                      URL of the Redmine server
+#   -k, --key                      Redmine API key
+#   
+# General options:
+#   -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

+#   
+# 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
