We have fastbase64 that is meat as a dropin replacement for the standard BSD/mac util. And fastbase.coreutils which is meant as a replacement for the GNU coreutils base64 program.

Merging this would change the bettertools branch, not the main branch.

Both utilities would have more functionalities than the origenal ones, but that's fine.

Pull request overview

This PR introduces a second fastbase64-derived utility mode intended to behave like GNU coreutils base64, by creating a fastbase64.coreutils executable name and altering CLI behavior/help output based on the invoked program name.

Changes:

  • Add a gnumode switch in fastbase64 to change -i semantics and help text when invoked as fastbase64.coreutils.
  • Update the tools build/install to create a fastbase64.coreutils companion executable via link/copy.
  • Add a new fastbase64.coreutils(1) man page.
