 """Build "SRPC" interfaces from specifications.
 
 SRPC interfaces consist of one or more interface classes, typically defined
 in a set of .srpc files.  The specifications are Python dictionaries, with a
 top level 'name' element and an 'rpcs' element.  The rpcs element is a list
 containing a number of rpc methods, each of which has a 'name', an 'inputs',
 and an 'outputs' element.  These elements are lists of input or output
 parameters, which are lists pairs containing a name and type.  The set of
 types includes all the SRPC basic types.
 
 These SRPC specifications are used to generate a header file and either a
 server or client stub file, as determined by the command line flag -s or -c.
