# convert_examples.tcl --
#
#
# reads the examples dir, checks if a file has been already converted
# in <target-dir> and compares their mtimes. If the file in
# <source-dir> is more recent the target dir is recreated.
# The script uses Rivet's escape_sgml_chars to convert examples code
# into text suitable to be inclued and displayed in XML/XHTML
# documentation
# NOTICE: This script requires Rivet, its scripts and
# libraries to be in the auto_path.
# usage:
#
# tclsh ./convert_examples
