tee — duplicate standard input

Original author: University of California, Berkeley
Ported by Duncan Bowring using amiport (AI-assisted porting toolkit).
Project: https://github.com/bdgscotland/amiport

Cross-compiled with m68k-amigaos-gcc for AmigaOS 3.x (68000+).
Tested on AmigaOS 3.1 via FS-UAE (11/11 tests passed).

Usage:
  tee [-ai] [file ...]

  -a   Append to files instead of overwriting them
  -i   Ignore the SIGINT signal (Ctrl-C on Amiga)

Examples:
  Echo hello | tee RAM:output.txt     ; prints "hello" and saves to file
  Echo hello | tee -a RAM:output.txt  ; appends "hello" to existing file
  Echo hello | tee RAM:a.txt RAM:b.txt ; writes to multiple files at once
  Type file.txt | tee T:backup.txt    ; copy file while backing up to T:

OpenBSD tee v1.15 (2023-03-04). BSD 3-Clause license.

Includes full source code (original POSIX and ported Amiga versions)
and PORT.md documenting every transformation applied.
