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:
----------------------------------------------------

  - Put all new variables in the variables list bellow
  - 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 list bellow
  - Put all new arrays in the GLOBAL_ARRAYS variable
  - If you are using an unix command, check if its already
    listed in the commands list. 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
