We should merge #184 first.

In polar2grid I think I called this --create-profile and nargs=?. That way I could provide a default HTML file name with info about the reader and writer being used and the current time.

I don't understand what you mean by "provide a default HTML file name". With nargs=? you'd be giving multiple HTML file names to write to? Info about the reader and writer, you mean by string substitution?

[djhoese]

Sorry. With nargs="?" and default=False you can pass only --create-profile to the CLI and args.create_profile will be None (if I remember correctly). Or you can do --create-profile profile_my_filename.html. Or if it isn't specified at all then args.create_profile is False. If it is None I then later set it to "{project_name}_{glue_name}_{start_time:%Y%m%d_%H%M%S}.html" where for P2G project_name is either "geo2grid" or "polar2grid", glue_name is <reader_name>2<writer_name> and start_time is the current time when the script is executed. I also allow the user to specify end_time in the format string.

I turned it into a context manager:

You'll notice I also print out a file:// version of the HTML path so in my Terminal on linux it is Ctrl + left click-able and opens in my browser.
