st: User-written commands and vce() support

[Richard Williams <Richard.A.Williams.5@ND.edu>]

One of the things that impresses me about Stata is that it is easy to 
write ml programs for it that support all sorts of options (including 
many that I have no idea what they do!)  Anyway, one of my programs 
is called oglm (available from SSC), and the following two commands both work:

oglm  warm yr89 male, vce(oim)
oglm  warm yr89 male, vce(robust)

Alas, the following does not:

. oglm  warm yr89 male, vce(bootstrap)
vcetype 'bootstrap' not allowed

So, my question is, what do I need to do to tweak my programs to 
support more of the vce options?
I don't explicitly define vce as an option in my program.  Instead, 
the option gets captured by this command:

mlopts ml_options, `options'

Is mlopts letting some vce options through while blocking others?  If 
so, do I need to explicitly include the vce otion in my syntax 
statement, and then check to make sure that the options specified are 
legit?  If so, is there some nice code I can just cut and paste?
