I know this has been a question many times asked/answered. But I have still difficulty to understand because TeX Live has different tree on Mac and is available also on Linux.
The question is simple:
I want to install, on MacTeX 2011, the beta version of Microtype package (for use with pdfTeX): microtype package (beta) on TLContrib
On the page there is 3 zip to download:
Which one should I pick? And where should I place it? (here: /Users/myname/Library/texlive/2011/texmf-var ?)
Should I issue some commands on the Terminal like those proposed on this post.
I also want to be able to (easily) revert to the stable package in case I got some issues with the beta package.
