[TxMt] Ruby 1.9 and LaTeXtra

[Alain Matthes]

Hi

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

Best Regards

Alain Matthes
