• http://club.myce.com/f52/determine-dvd-r-write-capability-ubuntu-306981/ not much luck yet

Dependencies

Ubuntu

• python-setuptools (?)
• python-virtualenv
• python-pip
• mercurial (won't be needed for a dpkg dependency, most likely)
• cdrkit (probably)
• dvd+rw-tools (probably)

Python

(Hopefully) see pip-requirements.txt once the project is closer to completion, and automatically install all these with pip.

• cmdln
• nose (for testing)
  • examples

Development installation

1. Install all Ubuntu dependencies
2. cd to the dir where you want the virtualenv containing the code to live.
3. virtualenv --no-site-packages lazers
4. cd lazers
5. . bin/activate
6. pip install -E . yolk (optional, but useful)
7. pip install -E . cmdln
8. pip install -E . nose (if you want to run the tests)
9. mkdir src
10. cd src
11. hg clone http://bitbucket.org/gmfreegeek/lazers/

Optical drive examination procedure

1. wodim dev=/dev/sr0 -prcap
   • Makes sure a drive is there
   • Gets a list of most capabilities
   • Does NOT distinguish DVD-R from DVD+R capability

or alternatively...

1. hal-find-by-capability --capability storage.cdrom to get a udi
2. lshal -u [udi] reveals the drive's capabilities one by one, including plusr, dvdram, etc. Dunno about lightscribe.
