DEPENDENCIES

Needed: 
VIF is a front-end to gcc, hence gcc dependency is obvious.

Optional: 
VIF can keep the intermediate C file, formatted as a classic listing file. 
To produce the file as pdf with the option -p, `ps2pdf' and `enscript' are required.


INSTALLATION

The makefile first builds the VIF runtime library, then a bootstrap VIF compiler. 
With the bootstrap VIF, FORTRAN source for the VIF runtime library is compiled and linked.

* Installation on Linux

  Install VIF from the command-line like so:

  $ ./configure
  $ make 
  $ make check
  $ sudo make install

* Installation on FreeBSD

  Compiling and running VIF requires some GNU utilities from packages or ports.
  Install VIF from the command-line like so:

  $ sudo pkg install bash gcc gmake gsed
  $ bash ./configure
  $ gmake 
  $ gmake check
  $ sudo gmake install
