buildname [-name <build name>] <build_* [build_* ...]>

buildname will call functions from the BuildName.pm module. The option 
-name paramater allows the caller to pass a build name to the specified 
functions to override the default of reading the name from 
_NTPostBlduild_logsuildname.txt.

At least one BuildName function must be given on the command line. The
complete list of functions available is documented in BuildName.pm

Example:

'buildname build_number build_branch' might return: '2420 main'

'buildname -name 2422.x86fre.lab02_n.010201-1120 build_date' would 
return: '010201-1120'
