Fortran WEB is a literate-programming system for writing Fortran programs. An FWEB file contains documented program text, including the Fortran code and the documentation that describes it.
FWEB processes the file to extract Fortran source for compilation and can also produce formatted documentation. The format is plain source text rather than a compiled Fortran program, and it can be used with Fortran development tools on multiple platforms.
Open a .fweb file with the FWEB tools associated with Fortran to process its code and documentation. Because it is a source file, it can also be viewed in any plain-text editor, although an editor will not build or document the program.
A .fweb file is normally processed rather than converted to another file format. FWEB can extract the Fortran source, which can then be compiled with a Fortran compiler, or generate formatted documentation from the source.
