Command-line utilities (libedit and readline).
There are two subdirectories:
\libedit. All the files here are
"non-MySQL" files, in the sense that MySQL AB didn't produce
them, it just uses them. It should be unnecessary to study the
programs in these files unless you are writing or debugging a
tty-like client for MySQL, such as
\readline subdirectory contains the
files of the GNU Readline Library, "a library for reading lines
of text with interactive input and history editing". The
