Each user of

The possible profile components are exemplified below. The only mandatory
entry is `Path:'. The others are optional; some have default values if
component can only appear once. Multiple appearances with trigger a

-.I \&.mh\(ruprofile
-may override the path of the
-.I context
-file, by specifying a \*(lqcontext\*(rq entry (this must be in
-lower-case). If the entry is not absolute (does not start with a
-\*(lq/\*(rq), then it is interpreted relative to the user's
-.B nmh
-directory. As a result, you can actually have more than one set of
-private sequences by using different context files.
