For developers using the git tree:

This source tree is based on the autotools suite from GNU to simplify
portability. Here are some things you should have on your system in order to
compile the git repository tree :

- GNU autotools (automake >=1.10, autoconf >=2.50, autoheader >=2.50)
  (make sure your system wide "automake" points to a recent version!)
- GNU Libtool >=2.2
  (for more information, go to http://www.gnu.org/software/autoconf/)

If you get the tree from the repository, you will need to use the "bootstrap"
script in the root of the tree. It calls all the GNU tools needed to prepare the
tree configuration.

INSTALLATION INSTRUCTIONS:

  - Download, compile and install the prerequisites.
  Then:
  $ ./configure
  $ make
  $ sudo make install
  $ sudo ldconfig

  If compiling from the git repository, run ./bootstrap before running
  the configure script, to generate it.

USAGE:

Please see doc/quickstart.txt to help you start tracing. You can also use the
-h/--help command on 'lttng' and all other commands offered in this tool (Ex:
lttng enable-event -h).
