Re: How do you use "archive" property reference to determine XPI install folder?

I figured this one out too:

archiveDir = dirGetParent(archive);

However, now I've discovered something even MORE annoying.  APIs are
not actually decompressed to the file system - they're only stored in
memory.

Now that I've determined what directory the API is in, and also how to
execute an external command, how the hell do I do something as simple
as copying a file contained in the API to somewhere else?

Don't tell me I need to execute an "unzip" command to get the API
decompressed to the file system, execute an external copy command,
then delete the just unzipped files?

I can't believe that this is so complex.  Why doesn't Mozilla have
built-in support for .jar file handling?  It would be *SO* much
simpler if I could just have a basic one liner to copy files in the
XPI into an existing Mozilla .jar...
