+# $EPIC: uniq.txt,v 1.2 2006/08/20 17:37:08 sthalik Exp $
+======Synopsis:======
+$__uniq__(<word list>)
+======Technical:======
+   * If the <word list> argument is omitted the empty string is returned.
+   * In all circumstances, any extra whitespace between words in the word list is lost in the return value.
+   * The implementation of this function is equivalent to:
+  fe ($*) x {
+    if (findw($x $function_return) == -1) {
+      push function_return $x
+    }
+  }
+   * This function uses a O(N^2) algorithm and can perform very slowly for large inputs.
+======Practical:======
+This function returns all of the words in <word list> after all of
+the duplicates are removed.
+======Returns:======
+list of the unique words in <word list>
+======Examples:======
+<file>
+$uniq(one two three two one)       returns "one two three"
+$uniq(one    two three  two one)   returns "one two three"
+$uniq(blah blah blah)              returns "blah"
+</file>
+======History:======
+This function first appeared in EPIC3.001.
