+.SS "Profile Lookup"
+Some
+.B nmh
+programs will look in more than just the user's 
+.I \&.mh\(ruprofile
+for profile entries.  In particular, 
+.BR mhbuild ,
+.BR mhshow ,
+.BR mhstore ,
+and
+.BR mhn 
+will also all look in a file specified by a program-specific
+environment variable (see below), and after that in 
+the system-installed profile (%etcdir%/mhn.defaults).  (The
+.B mhfixmsg
+program is similar, but doesn't consult an environment variable.)
+The first match found for a particular component will be used,
+allowing user-supplied entries to override those that are system-supplied.
+A profile component with a blank value field will "hide" any later
+occurrences of the component, and will make the entry appear to be
+absent.
