# XMI2TXT TCL
# Creates list of classes with variables and methods
# usage: cat my_xmi_file.xmi | ./xmi2txt.tcl
#
# Example output:
# companyHandler:
#   V mixed $this->db
#   M void __construct (mixed $db)
#   M bool add (string $name, int$parentid)
#   M bool edit (int $id, string $name, int $parentid)
#   M array getList (array $notids)
#   M array getDetails (int $id)
#   M int getVisitsByCompany (int $company)
#
# V = variable M = method
# M <output> <method name> (<parameter type> <parameter name>)
# V <type> <name inside class>
#
# Tested with: Ubuntu Dapper Linux
# XMI file was created with http://tech.motion-twin.com/php_php2xmi.html
#
# This script was created because I wanted to print classes and methods easily 
# without too much info on paper
