+SYNOPSIS
+ void add_xverb(string str)
+
+DESCRIPTION
+ This function is connected to the add_action() function. It
+ will set up the command str to trigger a call to the function
+ set up by the previous call to add_action().
+
+ add_xverb() differs from add_verb() in that only leading
+ characters of the input line must match with str. It basically
+ is the same as setting flag in add_action().
+
+ [marion Sun Jan 19 1992 Don't use it. This file is retained
+ because of somewhat nostalgic reasons.]
+
+HISTORY
+ Removed in LDMud 3.3 and LP "03.02.1@150",
+ obsoleted by add_action().
