No, I don't call "join" and "awk" directly from statist.

The test included "awk" and "join" because I wanted to check whether the
instructions that I wrote on the manual really work as I described. I was
testing the user manual, not only statist. The fixed width data file that I
created had some empty spaces where they normally are not found in real fixed 
width data files. This wasn't tested with the PNAD database that I used 
before to test --xcols. I can create a directory doc/example with some 
scripts and sample data files (but after the release of 1.3.0).

I liked the use of tests. They increase our trust in the code that we are
writting. Next time I add a feature to statist I will first write the result
as it have to be, and, then, write the code.

Best,

Jakson
