I would like to use ruby 1.9 under Snow 10.6
1) How to install Ruby 1.9 : Side by side with 1.8.7 or remove 1.8.7 ? What is the best solution ?
I will continue to compile LaTeX with TextMate
2) I'm interesting by the code of the command "Typset & View in Skim" of the bundle LaTeXtra and also by the command "Preview Tikz Picture"
I would like to know the important points in these codes, perhaps if it's possible to read some comments about the code
