# Run the "tidy" program over the files in a directory.
# The "tidy" program must be on your PATH.
#
# Usage:
#   sh tidy.sh <dir>
#
# The "tidy" program will be run on each HTML file in <dir>,
# and the output placed in the corresponding location in a new
# directory <dir>.tidy.  The console output from running "tidy" will
# be saved in a corresponding file with an additional .tidy extension.
#
# Non-HTML files will be copied without modification from <dir> to
# <dir>.tidy, so that relative links within the directory tree are
# unaffected.
