[CIG-SHORT] help-components for mac executable: Format and error question

[Brad Aagaard]

Rowena,

There are a couple different stages where we do validation of input in 
PyLith. For some very basic parameters, such as specifying a filename 
for the mesh, this is done very early via Pyre. So early, in fact, that 
the validation occurs before --help-components is processed. Other 
validation occurs after we have read in the mesh. As we have added more 
checking of parameters to prevent clearly inadmissible values, PyLith 
requires more info to be able to run --help-components.

Our current expectation is that users specify a minimum number of valid 
parameters in order to do anything at all, including using the 
--help-components arguments and pylithinfo.
