# xrs - detect unsorted cross references in section SEE ALSO
|
|
#
|
|
# Cross references in the SEE ALSO section should
|
|
# be sorted by section number, and then placed in alphabetical
|
|
# order and comma separated. For example:
|
|
#
|
|
# ls(1), ps(1), group(5), passwd(5).
|
|
#
|
|
# The last entry may be finished with a dot `.'
|
|
#
|
|
# or a source example:.
|
|
# .Sh SEE ALSO
|
|
# .Xr foo 1 ,
|
|
# .Xr bla 2 ,
|
|
# .Xr foobar 8
|
|
# .Sh HISTORY
|
|
#
|
|
# usage: xrs manpages ...
