over the internet, and install code that has been shared by others.  Guildhall
can handle dependencies, so when a program requires several libraries, and
each of those has further dependencies, all of the prerequisites for the
program can be installed in one go.")

the following aspects of Bash:

@itemize
@item aliases;
@item setting and getting Bash variables;
@item creating dynamic variables;
@item creating Bash functions with a Scheme implementation;
@item reader macro for output capturing;
@item reader macro for evaluating raw Bash commands.
@end itemize

To enable it, run:

@example
enable -f ~/.guix-profile/lib/bash/libguile-bash.so scm
@end example

and then run @command{scm example.scm}.")

     "Guile-Reader is a simple framework for building readers for GNU Guile.

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).")
