  "github_readme_excerpt": "# `bc`\n\n***WARNING: This project has moved back to GitHub temporarily; self-hosted Git\nforges are not working for me, so I am trying to replace them.***\n\nThis is an implementation of the [POSIX `bc` calculator][12] that implements\n[GNU `bc`][1] extensions, as well as the period (`.`) extension for the BSD\nflavor of `bc`.\n\nFor more information, see this `bc`\u0027s full manual.\n\nThis `bc` also includes an implementation of `dc` in the same binary, accessible\nvia a symbolic link, which implements all FreeBSD and GNU extensions. (If a\nstandalone `dc` binary is desired, `bc` can be copied and renamed to `dc`.) The\n`!` command is omitted; I believe this poses security concerns and that such\nfunctionality is unnecessary.\n\nFor more information, see the `dc`\u0027s full manual.\n\nThis `bc` also provides `bc`\u0027s math as a library with C bindings, called `bcl`.\n\nFor more information, see the full manual for `bcl`.\n\n## License\n\nThis `bc` is Free and Open Source Software (FOSS). It is offered under the BSD\n2-clause License. Full license text may be found in the [`LICENSE.md`][4] file.\n\n## Prerequisites\n\nThis `bc` only requires either:\n\n1.\tWindows 10 or later, or\n2.\tA C99-compatible compiler and a (mostly) POSIX 2008-compatible system with\n\tthe XSI (X/Open System Interfaces) option group.\n\nSince POSIX 2008 with XSI requires the existence of a C99 compiler as `c99`, any\nPOSIX and XSI-compatible system will have everything needed.\n\nPOSIX-compatible systems that are known to work:\n\n* Linux\n* FreeBSD\n* OpenBSD\n* NetBSD\n* macOS\n* Solaris* (as long as the Solaris version supports POSIX 2008)\n* AIX\n* HP-UX* (except for history)\n\nIn addition, there is compatibility code to make this `bc` work on Windows.\n\nPlease submit bug reports if this `bc` does not build out of the box on any\nsystem.\n\n## Build\n\nThis `bc` should build unmodified on any POSIX-compliant system or on Windows\nstarting with Windows 10 (though earlier versions may work).\n\nFor more complex build requirements than the ones below, see th",
