[R-pkgs] pgfSweave 1.1.1 Released

[Cameron Bracken]

The next release of pgfSweave is now on CRAN! pgfSweave has seen some
significant changes in the past couple of months.

The main new features are:

- Automatic code highlighting via the highlight package. This can be
turned off with the new `highlight` option.
- "Tidying" of source code output via the tidy option.
- Access to tikzDevice sanitization through a code chunk option `sanitize`
- Automatic addition of the \pgfrealjobname command if it does not
exist similarly to the addition of the \usepackage{Sweave} line.
- Setting tex.driver=latex will now (in addition to working) generate
an eps file

And of course bug fixes:

- Fixes for bunches of issues related to the changes in Sweave in R
2.12. I think these issues are now resolved (fingers crossed)
- keep.source actually works now.

See the NEWS file for the complete list of changes and the vignette
for information on now to use the new options.

Cheers!
