The PNNL Fortran Library (a.k.a. FLIB) is a set of general purpose Fortran 90 routines that can be used to simplify the development of programs with a batch-style input/output interface. Here, the term batch-style interface means that a program

1. reads set of input parameters from a file
2. performs one or more generally computation intensive tasks
3. saves the results of the calculation to a file

In addition to the mainly non-numeric routines used to build program interfaces, the PNNL Fortran Library includes some general purpose numerical routines for tasks such as (psuedo) random number generation. To get a better feel for the scope of the library, browse the FLIB Manual.
