= Short Version =
We can't build it to v2/testing yet because of the CR candidates so 
you'll have to build it yourself. You'll need it very soon since Mike is 
using new APIs in this version.

To build:

cd deps/okaara
tito build --rpm

= Long Version =
There are two new arguments for Option instances:

validate_func takes a function that will be applied by okaara if the 
user specifies that option. The supplied function should take a single 
argument (which will be the user-specified value) and if it's valid, the 
function should do nothing. If it's invalid, it should raise either 
ValueError or TypeError.

parse_func is similar except the provided function should return a 
value. The value will replace the user-specified value and be made 
available to the command when it's executed. That has the same behavior 
with ValueError and TypeError which means you can use it as the uber 
function and not have to split the validate and parse into two calls.

Mike brought up that the signature and use of standard exceptions (his 
suggestion) lets us pass in a number of standard calls, for instance:


If one of those two exceptions is raised, okaara will catch it and print 
a user-friendly indication of which argument failed validation and 
args[0] of the exception for more detail as to why.

Ping me or Mike with any questions.
