================
A tiny clipboard application for X.
# Building
----------
## Dependencies
To compile the project you will require:
* C99 compatible compiler (GCC is recommended)
* UNIX Make
* X11
## Compiling
The project is built using the `make' command. For debug information
append `DEBUG=1' to the command.
# Installation
--------------
Once the project is built, you can install by running `make install'. By
default the `PREFIX' variable is set to `/usr/local' (installing the
binary in `/usr/local/bin'). You can override this by appending
`PREFIX=<prefix>' to the install command.
