+##########################################################################
+# Title      :  urlencode - encode URL data
+# Author     :  Heiner Steven (heiner.steven@odn.de)
+# Date       :  2000-03-15
+# Requires   :  awk
+# Categories :  File Conversion, WWW, CGI
+# SCCS-Id.   :  @(#) urlencode  1.4 06/10/29
+##########################################################################
+# Description
+#   Encode data according to
+#       RFC 1738: "Uniform Resource Locators (URL)" and
+#       RFC 1866: "Hypertext Markup Language - 2.0" (HTML)
+#
+#   This encoding is used i.e. for the MIME type
+#   "application/x-www-form-urlencoded"
+#
+# Notes
+#    o  The default behaviour is not to encode the line endings. This
+#   may not be what was intended, because the result will be
+#   multiple lines of output (which cannot be used in an URL or a
+#   HTTP "POST" request). If the desired output should be one
+#   line, use the "-l" option.
+#
+#    o  The "-l" option assumes, that the end-of-line is denoted by
+#   the character LF (ASCII 10). This is not true for Windows or
+#   Mac systems, where the end of a line is denoted by the two
+#   characters CR LF (ASCII 13 10).
+#   We use this for symmetry; data processed in the following way:
+#       cat | urlencode -l | urldecode -l
+#   should (and will) result in the original data
+#
+#    o  Large lines (or binary files) will break many AWK
+#       implementations. If you get the message
+#       awk: record `...' too long
+#        record number xxx
+#   consider using GNU AWK (gawk).
+#
+#    o  urlencode will always terminate it's output with an EOL
+#       character
+#
+# Thanks to Stefan Brozinski for pointing out a bug related to non-standard
+# locales.
