---- pkg-comment ---
-Simple regular expression library from Plan 9
---- pkg-descr ---
-Libregexp9 is a port of Plan 9's regexp library.
-It is small and simple and provides the traditional
-extended regular expressions (as opposed to the
-current extended regular expressions, which add {}
-and various \x character classes, among other 
-complications).
-
-It handles Unicode in wide character or UTF8 format!

-.PP
-.B
-void regerror(char *msg)
-.SH DESCRIPTION
-.I Regcomp
-compiles a
-regular expression and returns
-a pointer to the generated description.
-The space is allocated by
-.IR malloc (3)
-and may be released by
-.IR free .
-Regular expressions are exactly as in
-.IR regexp9 (7).
-.PP
-.I Regcomplit
-is like
-.I regcomp
-except that all characters are treated literally.
-.I Regcompnl
-is like
-.I regcomp
-except that the
-.B .
-metacharacter matches all characters, including newlines.
-.PP
-.I Regexec
-matches a null-terminated
-.I string
-against the compiled regular expression in
-.IR prog .
-If it matches,
-.I regexec
-returns
-.B 1
-and fills in the array
-.I match
-with character pointers to the substrings of
-.I string
-that correspond to the
-parenthesized subexpressions of 
-.IR exp :
-.BI match[ i ].sp
-points to the beginning and
-.BI match[ i ].ep
-points just beyond
-the end of the
-.IR i th
-substring.
-(Subexpression
-.I i
-begins at the
-.IR i th
-left parenthesis, counting from 1.)
-Pointers in
-.B match[0]
-pick out the substring that corresponds to
-the whole regular expression.
-Unused elements of
-.I match
-are filled with zeros.
-Matches involving
-.LR * ,
-.LR + ,
-and 
-.L ?
-are extended as far as possible.
-The number of array elements in 
-.I match
-is given by
-.IR msize .
-The structure of elements of
-.I match 
-is:
-.IP
-.EX
-typedef struct {
-	union {
-	   char *sp;
-	   Rune *rsp;
-	} s;
-	union {
-	   char *ep;
-	   Rune *rep;
-	} e;
-} Resub;
-.EE
-.LP
-If
-.B match[0].s.sp
-is nonzero on entry,
-.I regexec
-starts matching at that point within
-.IR string .
-If
-.B match[0].e.ep
-is nonzero on entry,
-the last character matched is the one
-preceding that point.
-.PP
-.I Regsub
-places in
-.I dest
-a substitution instance of
-.I source
-in the context of the last
-.I regexec
-performed using
-.IR match .
-Each instance of
-.BI \e n\f1,
-where
-.I n
-is a digit, is replaced by the
-string delimited by
-.BI match[ n ].s.sp
-and
-.BI match[ n ].e.ep\f1.
-Each instance of 
-.L &
-is replaced by the string delimited by
-.B match[0].s.sp
-and
-.BR match[0].e.ep .
-The substitution will always be null terminated and
-trimmed to fit into dlen bytes.
-.PP
-.IR Regerror ,
-called whenever an error is detected in
-.IR regcomp ,
-writes the string
-.I msg
-on the standard error file and exits.
-.I Regerror
-can be replaced to perform
-special error processing.
-If the user supplied
-.I regerror
-returns rather than exits,
-.I regcomp
-will return 0. 
-.PP
-.I Rregexec
-and
-.I rregsub
-are variants of 
-.I regexec
-and
-.I regsub
-that use strings of
-.B Runes
-instead of strings of
-.BR chars .
-With these routines, the 
-.I rsp
-and
-.I rep
-fields of the
-.I match
-array elements should be used.
-.SH "SEE ALSO"
-.IR grep (1),
-.IR regexp9 (7)
-.SH DIAGNOSTICS
-.I Regcomp
-returns 
-.B 0
-for an illegal expression
-or other failure.
-.I Regexec
-returns 0
-if
-.I string
-is not matched.
-.SH HISTORY
-This particular regular expression was first written by Rob Pike for Plan 9.
-It has also appeared as part of the Inferno operating system.
-.SH BUGS
-There is no way to specify or match a NUL character; NULs terminate patterns and strings.

-.SH NAME
-regexp9 \- Plan 9 regular expression notation
-.SH DESCRIPTION
-This manual page describes the regular expression
-syntax used by the Plan 9 regular expression library
-.IR regexp9 (3).
-It is the form used by
-.IR egrep (1)
-before
-.I egrep
-got complicated.
-.PP
-A 
-.I "regular expression"
-specifies
-a set of strings of characters.
-A member of this set of strings is said to be
-.I matched
-by the regular expression.  In many applications
-a delimiter character, commonly
-.LR / ,
-bounds a regular expression.
-In the following specification for regular expressions
-the word `character' means any character (rune) but newline.
-.PP
-The syntax for a regular expression
-.B e0
-is
-.IP
-.EX
-e3:  literal | charclass | '.' | '^' | '$' | '(' e0 ')'
-
-e2:  e3
-  |  e2 REP
-
-REP: '*' | '+' | '?'
-
-e1:  e2
-  |  e1 e2
-
-e0:  e1
-  |  e0 '|' e1
-.EE
-.PP
-A
-.B literal
-is any non-metacharacter, or a metacharacter
-(one of
-.BR .*+?[]()|\e^$ ),
-or the delimiter
-preceded by 
-.LR \e .
-.PP
-A
-.B charclass
-is a nonempty string
-.I s
-bracketed
-.BI [ \|s\| ]
-(or
-.BI [^ s\| ]\fR);
-it matches any character in (or not in)
-.IR s .
-A negated character class never
-matches newline.
-A substring 
-.IB a - b\f1,
-with
-.I a
-and
-.I b
-in ascending
-order, stands for the inclusive
-range of
-characters between
-.I a
-and
-.IR b .
-In 
-.IR s ,
-the metacharacters
-.LR - ,
-.LR ] ,
-an initial
-.LR ^ ,
-and the regular expression delimiter
-must be preceded by a
-.LR \e ;
-other metacharacters 
-have no special meaning and
-may appear unescaped.
-.PP
-A 
-.L .
-matches any character.
-.PP
-A
-.L ^
-matches the beginning of a line;
-.L $
-matches the end of the line.
-.PP
-The 
-.B REP
-operators match zero or more
-.RB ( * ),
-one or more
-.RB ( + ),
-zero or one
-.RB ( ? ),
-instances respectively of the preceding regular expression 
-.BR e2 .
-.PP
-A concatenated regular expression,
-.BR "e1\|e2" ,
-matches a match to 
-.B e1
-followed by a match to
-.BR e2 .
-.PP
-An alternative regular expression,
-.BR "e0\||\|e1" ,
-matches either a match to
-.B e0
-or a match to
-.BR e1 .
-.PP
-A match to any part of a regular expression
-extends as far as possible without preventing
-a match to the remainder of the regular expression.

-%description
-Libregexp9 is a port of Plan 9's regexp library.
-It is small and simple and provides the traditional
-extended regular expressions (as opposed to the
-current extended regular expressions, which add {}
-and various \x character classes, among other 
-complications).
