--main misbehaviour on cflow 1.7

[Gary Partis]

Hello

I have some functions which are prefixed with an underscore, for example 
_func(). When using the --main directive, it can't find _func. Any other 
function can be specified and found, even those with an underscore within the 
name. The problem only happens when function name starts with an underscore.

Is this a known problem? Is there a work around? Or am I cracking up?

Cheers

Gary
