+# test suite
+
+This test suite is based on [sharness](http://mlafeldt.github.io/sharness/)
+
+## install
+
+It is installed (from toplevel dir) with:
+
+    git subtree add --squash --prefix t/sharness https://github.com/mlafeldt/sharness master
+
+and update from time to time with:
+
+    git subtree pull --squah --prefix t/sharness master
+
+Read http://blogs.atlassian.com/2013/05/alternatives-to-git-submodule-git-subtree/ for more info on git subtree, you can define a remote to simplify commands or contribute sharness from your fork
+
+## automation
+
+Although every test is executable by itselft an only depends on sharness, that's not operative. this test suite relays on [prove](http://search.cpan.org/dist/Test-Harness/bin/prove) and ancient and good-know [make](http://www.gnu.org/software/make/) to complete the test suite. Launch it with 
+
+    make 
+
+or
+
+    make DEFAULT_TEST_TARGET=prove
+
+## Credits
+
+Makefile was shamelessly stolen from [git-integration](https://github.com/johnkeeping/git-integration/blob/master/t/Makefile)
+
+Test cases are strongly based on [bash_ini_parser test suite](https://github.com/rudimeier/bash_ini_parser/blob/master/test/test.sh)
