+Usage: rdm-mailhandler [options] --url=<Redmine URL> --key=<API key>
+Reads an email from standard input and forward it to a Redmine server
+
+Required:
+  -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
+  -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:
+  rdm-mailhandler --url https://domain.foo/redmine --key secret \\
+                  --project foo \\
+                  --tracker bug \\
+                  --allow-override tracker,priority
