Thanks to IgorB for how-to, Andrea for Latex formatting, and Andrew for proofreading. Made a few corrections based on feedback and checked into GIT. (Andrea, note I have added a new section to Manual, Authors and Contributors, so you may want to checkout all from GIT because CinelerraGG_Manual.tex changed and it would be very helpful if you have time to verify that I did not forget something).
Thank you Phyllis, you did a great job and there is no need for further changes on the Latex code. I take this opportunity for a proposal. In order to entice more users to contribute to the manual I was thinking of not transposing the new additions into Latex right away. I propose to post the contributions to the mailing list in odt so that any user can propose, read and edit them. LibreOffice also offers the possibility of having multiple contributors on the same file so that it is easy to keep track of the various contributions. There is no longer the obstacle of Latex that requires long installations and then learning the language. Then, having arrived at the final version I can transpose it into Latex and Phyllis correct it and put it in the repository. An additional benefit is to increase the sense of community around CinGG; in my opinion with contributions from more people we can increase the quality of the manual. What do you guys think?
