Detailed Description

-- Command-line network-delta tool.

Todo:
Add a -z option to gzip/gunzip patches. This would be somewhat useful, but more importantly a good test of the streaming API. Also add -I for bzip2.
Todo:
If built with debug support and we have mcheck, then turn it on. (Optionally?)
Todo:
popt doesn't handle single dashes very well at the moment: we'd like to use them as arguments to indicate stdin/stdout, but it turns them into options. I sent a patch to the popt maintainers; hopefully it will be fixed in the future.
Todo:
Add an option for delta to check whether the files are identical.
