Man pages provide the help needed to configure and use Unix commands and are usually accessed through Terminal, but this is a clumsy and inconvenient way to view the pages.

Features:
• List of all available man pages on your system.
• Show only a section of the pages.
• Search for a man page by name or search within a page.
• Display man page in text or HTML (different pages look best in different formats).
• Step back & forward through recently viewed man pages.
• Live links to 'See Also' entries.
• 'Sticky notes' at the side to jump to sub-sections in a page.
• Bookmark frequently viewed pages.
• Choose a font and size for the display.
• Convenient buttons in the toolbar allow quick access to commonly used utilities.

Compatibility: OS X 10.11 or later, 64-bit processor
