update-qd.pl
============

Use this tool to update qd.c and/or qdinfo.dat with the data from 
Stanfords psummary.html file.

If the project/credit data in qdinfo.dat is not in sync with that in qd.c, 
the inconsistency will get worse as the data in psummary.html is only checked
against that of qdinfo.dat.

In general it does the following:
- Download psummary.html from Stanfords webserver
- Read the project/credit information from qdinfo.dat
- Compare the project/credit info from psummary.html to that of qdinfo.dat
- Generate a new qdinfo.dat with the original qdinfo.dat info and the updated 
  info from psummary.html
- Read the source of qd.c and grab its project/credit data
- Update the project/credit data in qd.c with that from psummary.html
- Save the updated qd.c and compile if requested with -c flag.
