"""Configure a list from a text file description. Usage: config_list [options] listname Options: --inputfile filename -i filename Configure the list by assigning each module-global variable in the file to an attribute on the list object, then saving the list. The named file is loaded with execfile() and must be legal Python code. Any variable that isn't already an attribute of the list object is ignored (a warning message is printed). See also the -c option. A special variable named `mlist' is put into the globals during the execfile, which is bound to the actual MailList object. This lets you do all manner of bizarre thing to the list object, but BEWARE! Using this can severely (and possibly irreparably) damage your mailing list! --outputfile filename -o filename Instead of configuring the list, print out a list's configuration variables in a format suitable for input using this script. In this way, you can easily capture the configuration settings for a particular list and imprint those settings on another list. filename is the file to output the settings to. If filename is `-', standard out is used. --checkonly -c With this option, the modified list is not actually changed. Only useful with -i. --verbose -v Print the name of each attribute as it is being changed. Only useful with -i. --help -h Print this help message and exit. The options -o and -i are mutually exclusive.
