Sinan is a build tool designed to build Erlang/OTP Projects, Releases and Applications. Sinan leverages the metadata artifacts provided by OTP to do a good job building, testing, releasing, etc with very little or no additional input from the developer.
By far the easiest way to get sinan is to download it from the downloads site.
Sinan has extensive further documentation in its wiki on github. Check there for more information.
The Sinan FAQ is available at here.
A community exists around Sinan and the other Erlware projects. You may participate in the community and ask questions by joining the erlware-questions mailing list.
To get started just cd into an OTP Application and type
sinan build
This will give you an fully built OTP application under the _build directory. You can then run the command
sinan shell
to get an erlang shell with all the paths pointing correctly to the various parts of your system.
If you want to get adventurous you can run all the eunit tests in your app by running:
sinan test
and finially, if you want to package up a normal erlang release tarball you can run
sinan dist
The tarball will end up in
<project-root>/_build/<release-name>/tar/<app-name>-<app-vsn>.tar.gz
To get a list of all tasks currently available run the command
sinan help
Hopefully thats enough to get you started, but sinan has many options to do various things with projects from small single app projects to very large multiple app projects. To get more information take a look at the sinan manual.
