APL-Library

APL is a functional programming language originally proposed in the
1950s and implemented by IBM in the 1960s. GNU APL is a copyleft
iinterpreter of the language. These workspaces offer functions not
specified by IS13551, the international standard specification for APL.

APL uses a suite of operators and functions represented by special
characters and many APL vendors use proprietary file formats. Files
in the library are utf-8 encoding where APL's special characters are
stored with their Unicode value.

To display these files one must have an appropriate font installed.
The Free Software Foundation offers one at http://ftp.gnu.org/gnu/unifont/

As the standard computer keyboard does not contain many of these
special APL characters you must reconfigure yours and you have many
options. File README-3-keyboard distributed with GNU APL offers many
ideas. I used Emacs and gnu-apl-mode.
