We have seen in the previous post how to build an headless xulrunner application.
My first use case was enabling the Mozilla Mccoy application to launch from command line. That allows me to build a bash script which create nightly builds of a firefox extension automatically updated by Firefox every day!.

Here is the resulting Mccoy version :

• Linux i686 patched build of Mccoy: mccoy-0.5-command-line.tar.gz
• Patch based on 0.5 official release: mccoy-0.5-command-line.patch

Now, a summary of each command line arguments :

# Create a new named public/private key
$ ./mccoy -createKey mykey
Creating key with name : mykey
Public key : MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDbV+ZGXs658dOm/+4YtT+VzT5JWzMFYiQ8155fnMkOJCina2yDEBq8Lvi5qF5SyoMDkqaYeO51LR+B4p1g7oWmBW9HbOz3eA9lD/AHUR1SHiJAX7RQq8v9sPSkYta+LyVrCMFgpTmhOWPUXOnwalmL7syGkXyjxHqHCYz+s3d22QIDAQAB
The key has been successfully created!
