[Newbies] Etoy tutorials on Squeakland and documentation in general

[lanas]

Folks,

  I'd like to go through the Etoy tutorials on Squeakland to
familiarize myself about them but mostly also to be able to show them
to our children as I find that Squeak is a very nice approach to
programming concepts.

  Thing is, what do I do with a .pr file ?  Such as
NewPaint_05.014.pr.  Do I simply file it in ?  Do I view it in Firefox
using a plugin ?

  This brings a related matter: documentation.  Not tutorials, but
complete documentation.  I have the Guzdial book on Squeak (the white
one) and it shows a lot of things, but is there an official
documentation that is not made of snippets of info but is a reference
to Smalltalk using Squeak ?

Cheers,
Al
