... ... 1.2.2 Elm

In addition to the basic signature instructions in 1.1 above, users of Elm
need to edit their ~/.elm/elmrc file so that it contains the following:

signature = ~/.signature
sigdashes = ON

Remember to delete any # characters before any variables you want
to set.  The defaults are indicated in comment lines starting with ###.

NOTE
====
The signature variable sets both the localsignature and
remotesignature variables.  If you want to have a different signature
for local mail (i.e., addresses that don't contain a ! or @) then you
can use the localsignature and remotesignature variables instead of
the signature variable.
