need_compile

This function uses the column <code>NeedsCompilation</code> of the package database
on CRAN to check if a package needes to be compiled. When it contains
C/C++/Fortran code, it has to be compiled. For such packages, we might need
to install additional system dependencies (e.g. libxml2-dev for the
XML package).

For a given R package ready for release, all its reverse
dependencies are downloaded from CRAN and checked on Travis CI, to make
sure the current development version of this package does not break
packages that depend on it. For packages with a lot of reverse
dependencies, they can be divided into groups, with each group checked on a
separate Travis virtual machine to avoid Travis timeout. Additional system
dependencies (Ubuntu) can be manually specified in a configuration file.
