nbfc -- The new brainfuck compiler

Installing nbfc is pretty much straight forward. On many unix-like systems,
running "make", followed by a "make install" is all you should need. If you run
into difficulties, please check the following:

1. Edit config.h and set CC and JAVAC to the names of your C compiler and your
Java compiler, respectively. nbfc will compile without a Java compiler, but it
will not be able to generate Java applications, of course. 

2. Edit the Makefile. You must have a lexical analyzer/scanner generator that
is compatible with lex (such as the default flex, or AT&T lex or Berkely lex). 
If you don't have flex installed, you must edit the line in the Makefile that
says "flex bf.l". However, I strongly recommend to install flex. Not only is it
technically well done, but also has nbfc not been tested with other lexers,
and although it doesn't use features unique to flex, it may in the future.

3. You must have a C compiler. Edit all the lines in the Makefile mentioning
gcc if you don't use the GNU C compiler.

4. You must have a yacc-compatible compiler-compiler. The default is bison.
Edit the line that says "bison -yd bf.y" if you don't use bison.

5. Run "make". Become root and run "make install".

6. Read the documentation with "man nbfc".
