Use the new "Signup" package in the .info file

See #578344: Create a "Signup" module package for the admin/build/modules page for more. You can now add the following to all the .info files for this project:

and your modules will show up next to the other signup-related modules in the new "Signup" section at admin/build/modules.

p.s. While I'm in your issue queue...

FYI, I've committed some recent changes to Signup that you might want to know about:
#581734: Improve the signup API: add hook_signup_data_alter(), hook_signup_create(), and hook_signup_update()
#578502: Move signup-related settings from node/N/edit to node/N/signups/settings
#581652: Add a {signup_log}.count_towards_limit column and adjust limit logic accordingly

If your module interacts with signup_status at all, you should also check out:
#359412: Move code for signup limits per status per node into a submodule
#581826: Fix status "modify signup count" code to actually do something
#581846: Cleanup the signup_status admin UI and provide status weights
and maybe:
#241869: Improve interface for setting number of signups allowed per status
