# Usage: write-dev-docs [FILE..]
#
# A file can be a tool name like "pt-archiver" or a module name like
# "Advisor.pm"; the ".pm" suffix is required. A file can be with
# or without a path. One or more file can be specified. If no files
# are specified, then dev docs for lib/* and bin/* are written.
# Files are only written if the original (e.g. bin/pt-archiver) is
# newer than the dev doc copy (e.g. docs/dev/tools/pt-archiver).
# Dev doc copies are necessary so that NaturalDocs does not write
# absolute paths in config/NaturalDocs/Menu.txt.
