built 0.3.2

built provides a crate with information from the time it was built.

built is used as a build-time dependency to collect various information about the build environment, serialize it into Rust-code and compile it into the final crate. The information collected by built include:

• Various metadata like version, authors, homepage etc. as set by Cargo.toml
• The tag or commit id if the crate was being compiled from within a git repo.
• The values of various cfg!, like target_os and target_arch.
• The features the crate was compiled with.
• The various dependencies, dependencies of dependencies and their versions cargo ultimately chose to compile.
• The presence of a CI-platform like Travis CI and AppVeyor.
• The used compiler and it's version; the used documentation generator and it's version.
