HowTo repackage Lightning for Linux and Windows

The purpose of this document is to provide a short tutorial on how to repackage Lightning so that it ships all binaries parts for Linux and Windows and can be installed in a shared profile.

Basically you'll need to:

download lightning-0.8-tb-linux.xpi and lightning-0.8-tb-win.xpi
rename both .xpi files to .zip and extract them to the same folder
create new subfolder ./platform/Linux_x86-gcc3/components
create new subfolder ./platform/WINNT_x86-msvc/components
move all *.so files from ./components to ./platform/Linux_x86-gcc3/components
move all *.dll files from ./components to ./platform/WINNT_x86-msvc/components
The final folder structure should look like

lightning.xpi
 + chrome
 + components
 + defaults
 + js
 + platform
    + Linux_x86-gcc3
       + components
    + WINNT_x86-msvc
       + components
 + chrome.manifest
 + install.rdf

open file ./install.rdf with text editor and search for em:targetPlatform
change the line to

   <em:targetPlatform>WINNT_x86-msvc</em:targetPlatform>
   <em:targetPlatform>Linux_x86-gcc3</em:targetPlatform>

package all files in a new zip archive and rename it from .zip to .xpi

Scripted version

Put the Windows and Linux XPIs in one directory, place this script in that same directory, and run it, to get a "lightning-0.x-tb-dual-boot.xpi" install file!

#/bin/bash

# This script performs the packaging necessary for creating a Lightning extension
# package compatible with both Windows and Linux.  This is based off the 
# instructions here: <https://wiki.mozilla.org/User:Ssitter/UnifiedLightning>
