1Format, part of the collection of [Boost C++ Libraries](http://github.com/boostorg), provides a type-safe mechanism for formatting arguments according to a printf-like format-string. User-defined types are supported by providing a `std::ostream operator <<` implementation for them. 2 3### License 4 5Distributed under the [Boost Software License, Version 1.0](http://www.boost.org/LICENSE_1_0.txt). 6 7### Properties 8 9* C++03 10* Header-only 11 12### Build Status 13 14Branch | Travis | Appveyor | Coverity Scan | codecov.io | Deps | Docs | Tests | 15:-------------: | ------ | -------- | ------------- | ---------- | ---- | ---- | ----- | 16[`master`](https://github.com/boostorg/format/tree/master) | [](https://travis-ci.org/boostorg/format) | [](https://ci.appveyor.com/project/jeking3/format-bhjc4/branch/master) | [](https://scan.coverity.com/projects/boostorg-format) | [](https://codecov.io/gh/boostorg/format/branch/master) | [](https://pdimov.github.io/boostdep-report/master/format.html) | [](http://www.boost.org/doc/libs/master/doc/html/format.html) | [](http://www.boost.org/development/tests/master/developer/format.html) 17[`develop`](https://github.com/boostorg/format/tree/develop) | [](https://travis-ci.org/boostorg/format) | [](https://ci.appveyor.com/project/jeking3/format-bhjc4/branch/develop) | [](https://scan.coverity.com/projects/boostorg-format) | [](https://codecov.io/gh/boostorg/format/branch/develop) | [](https://pdimov.github.io/boostdep-report/develop/format.html) | [](http://www.boost.org/doc/libs/develop/doc/html/format.html) | [](http://www.boost.org/development/tests/develop/developer/format.html) 18 19### Directories 20 21| Name | Purpose | 22| ----------- | ------------------------------ | 23| `benchmark` | benchmark tool | 24| `doc` | documentation | 25| `examples` | use case examples | 26| `include` | headers | 27| `test` | unit tests | 28| `tools` | development tools | 29 30### More information 31 32* [Ask questions](http://stackoverflow.com/questions/ask?tags=c%2B%2B,boost,boost-format): Be sure to read the documentation first as Boost.Format, like any other string formatting library, has its own rules. 33* [Report bugs](https://github.com/boostorg/format/issues): Be sure to mention Boost version, platform and compiler you're using. A small compilable code sample to reproduce the problem is always good as well. 34* [Submit Pull Requests](https://github.com/boostorg/format/pulls) against the **develop** branch. Note that by submitting patches you agree to license your modifications under the [Boost Software License, Version 1.0](http://www.boost.org/LICENSE_1_0.txt). Be sure to include tests proving your changes work properly. 35* Discussions about the library are held on the [Boost developers mailing list](http://www.boost.org/community/groups.html#main). Be sure to read the [discussion policy](http://www.boost.org/community/policy.html) before posting and add the `[format]` tag at the beginning of the subject line. 36 37
