*patplex* also attempts to find and read a global configuration file
called `patplex.rc`, unless the *-N* option is given. It looks in all
directories named by the *PATH* environment variable, appended with
-`../etc`. For example, then, if *PATH* is
-`/usr/local/bin:/bin:/usr/bin`, the directories `/usr/local/etc`,
-`/etc` and `/usr/etc` are searched for `patplex.rc`, in that
-order. Only the first file found is used, should there exist several.
+`../etc/ashd`. For example, then, if *PATH* is
+`/usr/local/bin:/bin:/usr/bin`, the directories `/usr/local/etc/ashd`,
+`/etc/ashd` and `/usr/etc/ashd` are searched for `patplex.rc`, in that
+order. Only the first file found is used, should there exist
+several. If the given 'CONFIGFILE' contains any slashes, it is opened
+by that exact name. Otherwise, it is searched for in the same manner
+as the global configuration file.
Should the global and the given configuration files conflict, the
directives from the given file take precedence.

In addition to the rules, a *match* stanza must contain exactly one

only the *handler* action is recognized:

'HANDLER' must be a named handler as declared by a *child* or

If the *match* stanza as a whole matches, 'TEMPLATE' is
expanded and installed as the rest string of the request
