Man pages belonging to programs are usually distributed together with those programs. Therefore, the Linux man-pages distribution mainly contains the pages for system calls and library routines, special devices, and file formats. However, it also contains documentation for a number of programs, in cases where the authors or maintainers of the program do not distribute man pages themselves.
The Linux man pages are maintained by Michael Kerrisk. Corrections and additions are welcome. The page undocumented (3) contains a list of routines present in glibc for which no man page is available yet.
