+# $EPIC: rpattern.txt,v 1.2 2006/08/19 06:07:20 sthalik Exp $
+======Synopsis:======
+$__rpattern__(<word> <pattern list>)
+======Technical:======
+   * If the <word> argument is omitted the empty string is returned.
+   * This function returns a space separated pattern list of all of the patterns in <pattern list> that match <word>.
+   * This is the complement to $[[rfilter]](), and the inverse of $[[pattern]]().
+   * Double quoted words are honored, but the double quotes will be lost in the return value.
+======Practical:======
+This function lets you "filter" <pattern list> through a word, keeping all
+of the patterns that match a given word, and discarding all of the patterns
+that do not match the given word.  If you have a list of patterns, some of
+which match a word (say, a nick!user@host string) and some of which don't,
+and you want to remove the ones that don't, this function will do that.
+======Returns:======
+The list of patterns from <pattern list> that match <word>.
+======History:======
+This function first appeared in "plus-2" (post-ircII, pre-EPIC)
+======Examples:======
+<file>
+$rpattern(foobar f* *oo* a* *c)     returns "f* *oo*"
+$rpattern(hello hello a* *lo*)      returns "hello *lo*"
+</file>
