Document! But do not take this task as an addition to developing. Here is an example of an integrated way of developing and socumenting at the same time.
The example shows a script which includes its own documentation. With simple tools, we generate man documentation from its output.
First of all, you need this formatted output: --version and --help. This example applies the "fortunes" script written in a previous post.
[rodolfoap] /home/rodolfoap > fortunes --version
