Cleaned up build autotools and docs.

- not tracking autotools-generated files; people building
  from source should have autotools installed already
- added autogen.sh
- updated build notes

logkeys keylogger - installation instructions
=============================================

Provided your GNU/Linux distribution doesn't include logkeys package
in its repositories, manual installation of logkeys from source is as
easy as cloning this repo or [downloading a zip of the
source](https://github.com/kernc/logkeys/archive/master.zip),
unzipping, and building:
unzipping, configuring, and building.

    $ unzip logkeys-master.zip
    $ cd logkeys-master/build
Prerequisites
-------------

You need autotools to build the code from source:

    apt-get update
    apt-get install -y autotools

Build and Install
-----------------

    $ unzip logkeys-master.zip     # or use git clone
    $ cd logkeys-master

    $ ./autogen.sh     # generate files for build
    $ cd build         # keeps the root and src dirs clean
    $ ../configure

    $ make
    $ su               # get root to install in system
    $ make install     # installs binaries, manuals and scripts

To uninstall logkeys, remove accompanying scripts and manuals:

    # make uninstall    # in the same src dir
    $ make uninstall    # in the same build dir

See README file for usage instructions, troubleshooting and other notes.

Cleaning after a build
----------------------

`autogen.sh` and `configure` generate many files which are ignored by
git.  All of these files can be removed from the project, e.g. to
force a clean build, with the following:

    git clean -xdf
