[aur-general] How to name package?

[Dave]

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).
