Clone it by git:

git clone https://github.com/chys87/tiary.git

or download a snapshot.

You will need autoconf, automake and autoconf-archive:

cd tiary
autoreconf --install -v

You will need ncurses, libxml2, re2, libbz2 and their development packages:

./configure --prefix=/where/you/want/to/install/it
make
make install

If you want to run unit tests (make check), you also need gtest.
