Strengths Comparison

.MAN Strengths

  • Universal Unix-like OS documentation since 1971.
  • Plain text with simple troff markup — tiny files.
  • Section system cleanly separates commands from APIs from config files.
  • Renders to terminal, PostScript, HTML, or PDF.
  • Every Unix programmer knows the format.

.T2T Strengths

  • Plain-text source → multi-format output.
  • Simple syntax.
  • Tiny implementation.

Limitations

.MAN — Limitations

  • Terse by design — bad for tutorials or beginner-friendly intros.
  • Troff syntax is arcane and difficult for modern authors.
  • No interactive examples or live-editable snippets.
  • Mostly replaced by web docs, cheat sheets, and --help output for modern tools.

.T2T — Limitations

  • Superseded by Pandoc.
  • Tiny ecosystem.
  • Limited modern tooling.

Frequently Asked Questions

MAN (Unix Man Page) is a document format used to store paginated text, with optional formatting, tables, images, hyperlinks, headers and footers. It sits in the documents & text family and is typically associated with a specific office suite or publishing pipeline that defined the format and ships the canonical reader.

T2T (txt2tags) is a document format used to store paginated text, with optional formatting, tables, images, hyperlinks, headers and footers. It sits in the documents & text family and is typically associated with a specific office suite or publishing pipeline that defined the format and ships the canonical reader.

Modern office suites — Microsoft Word, Google Docs, LibreOffice Writer, Apple Pages — open most MAN files with reasonable fidelity. If your installed software does not support MAN, convert to DOCX or PDF first using KaijuConverter; both open in virtually every reader, including free online viewers.

Modern office suites — Microsoft Word, Google Docs, LibreOffice Writer, Apple Pages — open most T2T files with reasonable fidelity. If your installed software does not support T2T, convert to DOCX or PDF first using KaijuConverter; both open in virtually every reader, including free online viewers.

Upload the MAN to KaijuConverter and pick DOCX, PDF, ODT, RTF, HTML, Markdown, or plain text. Our pipeline runs LibreOffice headlessly plus pandoc for text formats — the same engines behind professional document pipelines. Styles, tables, images, and hyperlinks survive the conversion intact.

Yes, to a high degree. Standard fonts, headings, lists, tables, images, hyperlinks and page structure transfer cleanly. Custom fonts substitute to the closest match if not embedded; obscure layout features unique to MAN (frames, legacy macros) may flatten to static content in the target format.
