Why did you decide to go with your own custom solution (that's what is
implied by your message, sorry if it's not the case) instead of

contributing to Kiwix so that other projects can benefit from this all

; aka the reader, the tools, the standard, etc.

Sorry if you find it offensive. I never meant it like that. We released the CD/DVD in 2010 April. The reasons for developing Wiki2CD is documented at http://thottingal.in/blog/2010/04/17/mlwikioncd/ and http://shijualex.wordpress.com/2010/04/24/creating-malayalam-wikipedia-cd/
