Avoid the Typical Working Directory Pain When Using 'knitr'
Description
An extension of 'knitr' that adds flexibility in several
ways. One common source of frustration with 'knitr' is that it assumes
the directory where the source file lives should be the working directory,
which is often not true. 'ezknitr' addresses this problem by giving you
complete control over where all the inputs and outputs are, and adds several
other convenient features to make rendering markdown/HTML documents easier.
