Documentation Aids

• Most library and system functions are documented in man pages. These pages may be read in text mode (the 'man' command) or using a GUI man pages reader ('xman', 'tkman', etc).
  
  
• Various tools come with info pages. These are forms of primitive hypertext pages. 'info' (and also emacs) can read such pages. There is also a "info2html" CGI script that allows reading info pages using a web browser.
  
  
• Many tutorials exist, some of them come as part of the LDP (Linux Documentation Project), and are available on the Web.
