Provide a TGCommand base class within TurboGears 2.x core

[mcfletch]

I've got a recipe for setting up a TurboGears CLI command. It sets up tg.config, SQLAlchemy, and if lang is defined in the config, attempts to set up i18n (thanks to tmu).

This *seems* like it is functionality that should be available by default from TurboGears. There's enough black-magic stuff necessary that it really seems it shouldn't be something we're asking the (new) user to know how to do.

TGCommand base-class

[jorge.vargas]

+1 this must go into 2.1. I have about 3 half done implementations on several projects.

Can you provide an rst file explaining usage? Do we have to put an entry in setup.py to use this?

[mcfletch]

There is a documented (short) description in the 2.1 documentation which describes a much smaller approach to this. The TGCommand module doesn't currently have any test-cases. Percious suggests that we not include TGCommand without tests.

TGCommand is basically a real-world example of what is needed to prevent cron-bombing and otherwise creating an official command, but there's some question as to whether people really *want* that, or just want a simple couple-of-line script to integrate into their general code-bases.

Suggestion is to make tgcommand into tgext.tgcommand (i.e. an extension module).

[mcfletch]

Okay, there is now a tgext.command extension which can be installed. The README.txt in this package is basically the original blog post updated for the new packaging. Still needs tests and the like.
