Investigate the use of unit tests. Not only can they check code compliance,
but they also force you to define what code compliance is. Search the web for
"extreme programming". There's some books about the subject too.

Nah, they're just Old School concerns :) Seriously, those mechanisms do help
catch stupid bugs, but reliance on those issues can sometimes reduce the

Any team environment will enforce a coding style. Indendation style is always
a part of this. This is a dead herring.

You've just got to move the interface and component specifications up from
the code into documentation (where, IMO, it belongs.) and enforce component
compliance with unit tests.

Programmers must be disciplined anyway, again IMO. This idea that programmers
can just write whatever they damn well like, with little regard for what
other people are diong (an idea propogated mostly by the "write it any damn
way you like" ideology of Perl) is extremely detrimental to a working team.

Well, there you have (some) of them, hope they help :)
