This document was written in [Markdown], with the book itself being generated using [mdBook]. During development [mdbook-linkcheck] was used to verify the links.
**hhh** itself uses several packages.
- [chrono] is used to get the current UTC time and date
- [clap] is used to process the command line arguments
- [directories-next] is used to find the configuration directory
- [log] and [env-logger] are used to provide error and debugging output
- [num] provides arbitrary-precision numbers
- [tempfile] is used to create temporary files during testing
- [termsize] is used to get the terminal width
- [textwrap] is used to wrap text nicely
- [trivet] is used to implement the binary description language parser
