byacc:    Berkeley Yacc is an LALR(1) parser generator.  Berkeley Yacc
byacc:    has been made as compatible as possible with AT&T Yacc.  Berkeley
byacc:    Yacc can accept any input specification that conforms to the AT&T
byacc:    Yacc documentation.  Specifications that take advantage of 
byacc:    undocumented features of AT&T Yacc will probably be rejected.

byacc:    If you skip this package and install GNU bison, a /usr/bin/yacc
byacc:    shell script will be created which will allow you to use bison
byacc:    instead. (It contains 'bison -y $*')

g77:      GNU Fortran-77 compiler, version 0.5.19.1.
g77:
g77:      GNU Fortran, or g77, is designed as a free replacement for, or 
g77:      alternative to, the UNIX f77 command.  (Similarly, gcc is designed as
g77:      a replacement for the UNIX cc command.)

gmake:    GNU make utility 3.74.
gmake:
gmake:    This is the GNU implementation of make, which was written by Richard
gmake:    Stallman and Roland McGrath.  The purpose of the make utility is to
gmake:    determine automatically which pieces of a large program need to be 
gmake:    recompiled, and issue the commands to recompile them.  
gmake:
gmake:    This is needed to compile just about any major C program, including
gmake:    the Linux kernel.

m4:
m4:       This is release 1.4 of GNU m4, a program which copies its input to the
m4:       output, expanding macros as it goes. m4 has built-in functions for
m4:       including named files, running Unix commands, doing integer 
m4:       arithmetic, manipulating text in various ways, recursion, etc...  
m4:       Macros can also be user-defined, and can take any number of arguments.
