 ==Building from Source Code==
 Let's build the latest and greatest version of the popular, open-source statistics package--R.  We can download the source code from a mirror site right here in Bristol!

-In common with many other projects, the R distribution uses something called the '''automake''' package which creates makefiles for subsequent use in compiling the source code.  The typical pattern of commands in this situation is to run '''configure''', followed by '''make''', possibly some sort of test, and finally '''make install''' to complete the software installation.
+It's common to find files named '''README''' and '''INSTALL''', which will give details of the project and installation instructions, respectively.
 Configure scripts often follow convention when it comes to the options that they will accept.  For example:
