# change python1.5 to whatever is needed on your system to invoke python
#
# Retrieves a single file specified as a url and stores it locally.
#
# Calling sequence:
# urlget.py [-v] [-tmp tmpdir] [-] [http,ftp][://hostname][/]directoryname/file [local_filename]
#
# Options:
# -v - Print version number and exit
# -tmp - Uses tmpdir if one is provided, else, uses /tmp
# - - use store the file in current dir, with the same filename as the url
# local_filename - if provided, store the url in the specified file [relative to CWD]
# Notes:
# If the url has a .gz or .Z suffix, the url is uncompressed
# The uncompresion is not done if local_filename is specified [or the option '-' is used]
# If the url is neither ftp, nor http, then a local file copy is assumed.
