description = "Splits a file into pieces based on context patterns (line numbers or regex matches), writing each piece to a sequentially-named output file (`xx00`, `xx01`, …). Writes new files in the current directory unconditionally, so the bare invocation is a local-filesystem write. The macOS BSD form supports `-k`/`-s`/`-f`/`-n`; the GNU form (`gcsplit` via Homebrew, or `csplit` on Linux) adds `--prefix`/`--suffix-format`/`--digits`/`--keep-files`/`--quiet`/`--elide-empty-files`/`--suppress-matched`. POSIX utility with a frozen surface."
