-.Sh NAME
-.Nm bm_comp ,
-.Nm bm_exec ,
-.Nm bm_free
-.Nd Boyer-Moore string search
-.Sh SYNOPSIS
-.In sys/types.h
-.In bm.h
-.Ft bm_pat *
-.Fn bm_comp "const unsigned char *pattern" "size_t patlen" \
-    "const unsigned char freq[256]"
-.Ft unsigned char *
-.Fn bm_exec "bm_pat *pdesc" "unsigned char *text" "size_t len"
-.Ft void
-.Fn bm_free "bm_pat *pdesc"
-.Sh DESCRIPTION
-These routines implement an efficient mechanism to find an
-occurrence of a byte string within another byte string.
-.Pp
-.Fn bm_comp
-evaluates
-.Fa patlen
-bytes starting at
-.Fa pattern
-and returns a pointer to a structure describing them.
-The bytes referenced by
-.Fa pattern
-may be of any value.
-.Pp
-The search takes advantage of the frequency distribution of the
-bytes in the text to be searched.
-If specified,
-.Ar freq
-should be an array of 256 values,
-with higher values indicating that the corresponding character occurs
-more frequently.
-(A less than optimal frequency distribution can only result in less
-than optimal performance, not incorrect results.)
-If
-.Ar freq
-is
-.Dv NULL ,
-a system default table is used.
-.Pp
-.Fn bm_exec
-returns a pointer to the leftmost occurrence of the string given to
-.Fn bm_comp
-within
-.Ar text ,
-or
-.Dv NULL
-if none occurs.
-The number of bytes in
-.Ar text
-must be specified by
-.Ar len .
-.Pp
-Space allocated for the returned description is discarded
-by calling
-.Fn bm_free
-with the returned description as an argument.
-.Pp
-The asymptotic speed of
-.Fn bm_exec
-is
-.Pf O Ns Pq len / patlen .
