+# Wrapper scripts to various mail agents
+
+Only needed if your system does not provide a local MTA (e.g *sendmail*) and/or a POSIX *mailx* compatible mail command.
+
+To activate, choose a suitable one then place it somewhere in the path (*/usr/local/bin* is recommended), name or symlink it to *mail* and give it execute permission to anyone.
+
+To use them with *crond*, you may need the *cronmail* converter script, which can accept sendmail-formatted mail and convert it into a suitable *mailx* call. You can usually set this script as a mail sender for *crond* using the *CRONDARGS* environment variable.

+# It is primarily designed to use with crond. To activate
+# use CRONDARGS="-m pathname_to_cronmail" in/etc/default/cron or
