Firma Development Policy
------------------------

This policy helps control all development steps to keep a clean and junk-free
code. In the future this procedure can be automatic.

After any addition to firma, check the following:
-------------------------------------------------

- If a new variable has to be declared via a config-file,
  remember to set it to be created in the NewList function.

- Put all new functions in the FUNCTIONS variable.

- Put all new global variables in the GLOBAL_VARS variable.

- If you are using an unix command, check if it's already
  listed in the commands list bellow. If it's not, please
  add it.

Variables usage
---------------

- Global vars: uppercase, with spaces replaced by underscores.

- Local vars: lowercase, with spaces replaced by underscores and
              declared using "local".

- Attention to variables initialization, unset all vars after use.
