I would like to create a new package for lightning, which is the calendar extension for Thunderbird. I currently manage lightning-nightly for 32-bit systems, but for 64-bit systems (which I'm using now), I have to build the extension from source. This process initially downloads a lot of files, so if I created a package for this, it would take an hour to download and build a 1.2MB extension. Thus, I was going to build the extension on my computer and upload the XPIs to a server. However, I'm not sure what I should name the package and keep track of the versions. The process is: use mercurial to clone the comm-central code, then run a python script which will update the source with cvs. After that, I can run make to build the lightning extension, upload it to a server, and then allow anyone to download it. To update, I need only to run the python script and rebuild. Any suggestions on how the package should be named? Maybe -hg or -src? I'm also not sure which package version to use (since I may only update the XPI itself once a week/month).
