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

Abstract: this policy helps control all development
          steps to keep a clean and junk-free code.

In the future this procedure will be automatic.

1 - 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.

2 - 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.
