+# $EPIC: urldecode.txt,v 1.4 2009/08/29 23:21:45 jnelson Exp $
+======Synopsis:======
+$__urldecode__(<url-encoded-text>)
+======Technical:======
+This function performs the reverse-rfc3986 transformation on
+<url-encoded-text>.  Each byte of input in <url-encoded-text> is
+copied to the output, except that when the 0x25 value ("%") is found
+followed by two hexidecimal digits (0-9 or A-F), those three
+characters are converted into the corresponding byte.
+For example, "%20" in the <url-encoded-text> is replaced with a space.
+Unfortunately, because everything in the client is done as a C string, if
+the <url-encoded-text> contains a nul, or an encoded nul ("%00"), you won't
+see any data after that point.
+This function has been superceded by [[xform]] which has a URL transform.
+======Practical:======
+This can be used to de-mangle text that has been passed through
+$[[urlencode]]().
+======Returns:======
+The input <url-encoded-text> with url-encoded-sequences substituted
+for the equivalent punctuation mark.
