Erlang/OTP ========== **Erlang** is a programming language used to build massively scalable soft real-time systems with requirements on high availability. Some of its uses are in telecom, banking, e-commerce, computer telephony and instant messaging. Erlang's runtime system has built-in support for concurrency, distribution and fault tolerance. **OTP** is set of Erlang libraries and design principles providing middle-ware to develop these systems. It includes its own distributed database, applications to interface towards other languages, debugging and release handling tools. ERTS and BEAM ------------- **BEAM** is the name of the virtual machine where all Erlang code is executed. Every compiled Erlang file has the suffix .beam. The virtual machine is sometimes referred to as the emulator. **ERTS** is the Erlang Runtime System where the BEAM, kernel and standard libraries amongst others are included. More information can be found at [erlang.org] [1]. Building and Installing ----------------------- Information on building and installing Erlang/OTP can be found in the [$ERL_TOP/HOWTO/INSTALL.md] [5] document. Contributing to Erlang/OTP -------------------------- Here are the [instructions for submitting patches] [2]. In short: * Go to the JIRA issue tracker at [bugs.erlang.org] [7] to see reported issues which you can contribute to. Search for issues with the status *Contribution Needed*. * We prefer to receive proposed updates via email on the [`erlang-patches`] [3] mailing list or through a pull request. * Pull requests will be handled once everyday and there will be essential testing before we will take a decision on the outcome of the request. If the essential testings fails, the pull request will be closed and you will have to fix the problem and submit another pull request when this is done. * We merge all proposed updates to the `pu` (*proposed updates*) branch, typically within one working day. * At least once a day, the contents of the `pu` branch will be built on several platforms (Linux, Solaris, Mac OS X, Windows, and so on) and automatic test suites will be run. We will email you if any problems are found. * If a proposed change builds and passes the tests, it will be reviewed by one or more members of the Erlang/OTP team at Ericsson. The reviewer may suggest improvements that are needed before the change can be accepted and merged.
