Squirrelmail plugin packaging naming

[Tim Jackson]

There are a couple of Squirrelmail plugins I'd like to package. I've 
worked out things from the packaging side and been successfully using 
them for a while, but I'm not sure about the naming. Let's take for 
example the change_pass plugin. Here are some viable options for naming:

1. squirrelmail-plugin-change_pass
2. squirrelmail-plugin-change-pass
3. squirrelmail-change_pass
4. squirrelmail-change-pass

Option 1 from the above is what I've used to date, with the following 
reasoning:

a) squirrelmail-XXX as opposed to squirrelmail-plugin-XXX makes it sound 
like XXX is a subpackage of squirrelmail as opposed to some random third 
party plugin that is completely separate. The use of "*-plugins-*" is 
not without precedent; see libopensync for example.

b) Although underscores are not normally allowed in names, use of 
"change_pass" as opposed to "change-pass" makes sense because the 
PackageNamingGuidelines say "...packages where the upstream name 
naturally contains an underscore are excluded from this". In this case, 
underscores are conventionally used by Squirrelmail plugins and this is 
no exception - see upstream at 
http://www.squirrelmail.org/plugin_download.php?id=21&rev=1072 .

Comments welcome.

Thanks,

Tim
