three convenience functions for filenames and extensions (just to save some typing efforts)
a pandoc wrapper; closes #206
roxygenize
adapt to Shiny 0.4 API
disable the progress bar
a javascript snippet to toggle visibility of R source blocks in HTML, but it is said Wolfram has patent on this feature, which is the most ridiculous thing on this planet; I hope nobody is going to send me to jail because of this
use r62130 of r-devel to add vignette engines: now we specify the file patterns and (optionally) the package name
*.Rhtml vignettes are registered in knitr as well
use sans_ext() and sub_ext() for slightly shorter code, because it is a common task to replace file extensions
tweak the error message
roxygenize
bump version
