IF YOU ARE USING A PRODUCT FROM THE C++ FAMILY (C++lint, LintPlusPlus):

If this is a new order, you don't need to worry about your serial number.

If this is for a renewal:

Please enter your serial number(s) in the space provided so we can be
sure to credit the appropriate account.

There are three options to find your serial number:
1. If using the Cleanscape GUI, the serial number is embedded in the
   "About Cleanscape C++lint" dialog box accessed from the Help menu.

2. If using the command line, the serial number is returned by running
   cpplint -version
   
3. The serial number is located in file 
   c:\progra~1\cleanscape\cpplint\main\serno.txt
   


IF YOU ARE USING A LEGACY PRODUCT (Fortran-Lint):

There are no serial numbers for the legacy products.  Please email 
sales@cleanscape.net with your contact info if different than that on
the credit card.
