4.11. Optional upstream source location: debian/watch

This is an optional, recommended configuration file for the uscan utility which defines how to automatically scan ftp or http sites for newly available updates of the package. This is also used by some Debian QA tools to help with quality control and maintenance of the distribution as a whole.

If the upstream maintainer of the software provides OpenPGP signatures for new releases, including the information required for uscan to verify signatures for new upstream releases is also recommended. To do this, use the pgpsigurlmangle option in debian/watch to specify the location of the upstream signature, and include the key or keys used to sign upstream releases in the Debian source package as debian/upstream/signing-key.asc.

For more information about uscan and these options, including how to generate the file containing upstream signing keys, see uscan(1).
