[Factor-talk] Documentation for the peg.ebnf vocabulary

I've finally written some documentation for the peg.ebnf vocabulary. This documents the various ways of using it (EBNF:, [EBNF ... ENBF] and ) as well as the syntax for the EBNF language. Let me know (or provide patches!) if I left anything out or if anything is badly written. You can get it now f

[Factor-talk] Fixed some unmaintained vocabs

[Factor-talk] Amazon S3 vocab

A while back I wrote a vocab for using Amazon S3 (Simple Storage Service) from Factor so I could archive tinyvid videos on S3. I've tidied this up a bit and made it available. It's in the 's3' branch of my git repository: git://double.co.nz/git/factor.git Hopefully it can be included in the main
