# tk
|
|
tk is my Guile toolkit.
|
|
Each unit contains a group of tools I commonly used together or with a
|
|
particular module.
|
|
|
|
`make; sudo make install` Will install source files to `(%site-dir)` and
|
|
compiled versions to `(%site-ccache-dir)`. All units are installed under a
|
|
folder named `tk/` and so are imported using `(use-modules (tk <unit>))`.
