   (long-description
    "Many computer users need to manipulate text files: extract and then
operate on data from parts of certain lines while discarding the rest, make
changes in various text files wherever certain patterns appear, and so on.
To write a program to do these things in a language such as C or Pascal is a
time-consuming inconvenience that may take many lines of code.  The job is
easy with awk, especially the GNU implementation: Gawk.

The awk utility interprets a special-purpose programming language that makes
it possible to handle many data-reformatting jobs with just a few lines of
code.")

user-defined and can take any number of arguments.  Besides just doing macro
expansion, m4 has builtin functions for including named files, running UNIX
commands, doing integer arithmetic, manipulating text in various ways,
recursion etc...  m4 can be used either as a front-end to a compiler or as a
macro processor in its own right.")

    "GMP is a free library for arbitrary precision arithmetic, operating on
signed integers, rational numbers, and floating point numbers.  There is no
practical limit to the precision except the ones implied by the available
memory in the machine GMP runs on.  GMP has a rich set of functions, and the
functions have a regular interface.

The main target applications for GMP are cryptography applications and
research, Internet security applications, algebra systems, computational
algebra research, etc.

GMP is carefully designed to be as fast as possible, both for small operands
and for huge operands.  The speed is achieved by using fullwords as the basic
arithmetic type, by using fast algorithms, with highly optimised assembly
code for the most common inner loops for a lot of CPUs, and by a general
emphasis on speed.

GMP is faster than any other bignum library.  The advantage for GMP increases
with the operand sizes for many operations, since GMP uses asymptotically
faster algorithms.")

The idea is to make it easy to build procedures that extend Guile’s read
procedure. Readers supporting various syntax variants can easily be written,
possibly by re-using existing “token readers” of a standard Scheme
readers. For example, it is used to implement Skribilo’s R5RS-derived
document syntax.

Guile-Reader’s approach is similar to Common Lisp’s “read table”, but
hopefully more powerful and flexible (for instance, one may instantiate as
many readers as needed).")
