+.SH NAME
+apropos \- search the manual page names and descriptions
+.SH SYNOPSIS
+.B apropos
+.RB [\| \-dhV \|]
+.RB [\| \-r \||\| \-w\c
+\|]
+.RB [\| \-m
+.IR system \|[\|,.\|.\|.\|]\|]
+.RB [ \-M
+.IR path \|]
+.I keyword
+\&.\|.\|.
+.SH DESCRIPTION
+Each manual page has a short description available within
+it.
+.B apropos
+searches the descriptions for instances of
+.IR keyword .
+
+.I keyword
+may contain wildcards
+.RB ( \-w )
+or be a regular expression
+.RB ( \-r ).
+Using these options,
+it may be
+necessary to quote the
+.I keyword
+or escape (\\) the special characters to stop the shell from interpreting them.
+
+The standard matching rules allow matches to
+be made against the page name and word boundaries in
+the description.
+.SH OPTIONS
+.TP
+.B \-d, \-\-debug
+Print debugging information.
+.TP
+.B \-r, \-\-regex
+Interpret each keyword as a regular expression.
+Each keyword will be matched against the page names and the descriptions
+independently. It can match any part of either. The match is not limited to
+word boundaries.
+.TP
+.B \-w, \-\-wildcard
+Interpret each keyword as a pattern containing shell style wildcards.
+Each keyword will be matched against the page names and the descriptions
+independently. Only if an expanded keyword matches an entire description or
+page name, will a match be found.
+.\"
+.\" Due to the rather silly limit of 6 args per request in some `native'
+.\" *roff compilers, we have do the following to get the two-line
+.\" hanging tag on one line. .PP to begin a new paragraph, then the
+.\" tag, then .RS (start relative indent), the text, finally .RE
+.\" (end relative indent).

+If this system has access to other operating system's manual page
+descriptions, they can be searched using this option.
+To search NewOS's manual page descriptions,
+use the option
+.B \-m
+.BR NewOS .
+
+The
+.I system
+specified can be a combination of comma delimited operating
+system names.
+To include a search of the native operating system's
+.B whatis
+descriptions, include the system name
+.B man
+in the argument string.
+This option will override the
+.RB $ SYSTEM
+environment variable.
+.RE
+.TP
+.BI \-M\ path ,\ \-\-manpath= path
+Specify an alternate set of colon delimited, manual page hierarchies to search.
+By default,
+.B apropos
+uses the
+.RB $ MANPATH
+environment variable unless it is empty or unset in which case it will
+determine an appropriate manpath based on your
+.RB $ PATH
+environment variable.
+This option overrides the contents of
+.RB $ MANPATH .
+.TP
+.B \-h, \-\-help
+Print a help message and exit.
+.TP
+.B \-V, \-\-version
+Display version and author information.

+Nothing was found that matched the criteria specified.
+.SH ENVIRONMENT
+.TP
+.B SYSTEM
+If
+.RB $ SYSTEM
+is set, it will have the same effect as if it had been specified as the
+argument to the
+.B \-m
+option.
+.TP
+.B MANPATH
+If
+.RB $ MANPATH
+is set, its value is interpreted as the colon delimited, manual page hierarchy
+search path to use.
+.TP
+.B POSIXLY_CORRECT
+If
+.RB $ POSIXLY_CORRECT
+is set, even to a null value, the default
+.B apropos
+search will be as an extended regex
+.RB ( \-r ).
