+Besides general regression testing to ensure everything still works
+with nawk instead of gawk, following GNU awk extensions should be implemented
+or handled somehow (the list is probably incomplete, please add entries
+if anything is missing):
+
+* String functions: gensub() (partly done, finish backref. support)
+* (done) Time functions: strftime(), systime()
+* --posix flag, which would switch off nawk extensions over POSIX awk (?)
+* special file names: /dev/pid, /dev/ppid, /dev/pgrpid, /dev/user,
+ /dev/stdin, /dev/stdout, /dev/stderr, /dev/fd/X
+* special variables: ARGIND, ERRNO, FIELDWIDTHS, IGNORECASE, RT
+
+Also, the manpage should be improved to be generally more helpful
+and document extensions over what POSIX says about awk.
+
+Other misc:
+* run.c: don't limit files[] to FOPEN_MAX (which is ridiculously low),
+ make the limit the current process open file limit
+* nawk doesn't permit empty RE, like
+// { do_something; }

+.Sh NAME
+.Nm awk
+.Nd pattern-directed scanning and processing language
+.Sh SYNOPSIS
+.Nm
+.Op Fl F Ar fs
+.Op Fl v Ar var=value
+.Op Fl safe
+.Op Fl d Ns Op Ar N
+.Op Ar prog | Fl f Ar filename
+.Ar
+.Nm
+.Fl V
+.Sh DESCRIPTION
+.Nm
+is the Bell Labs' implementation of the AWK programming language as
+described in the
+.Em The AWK Programming Language
+by
+A. V. Aho, B. W. Kernighan, and P. J. Weinberger.
+.Pp
+.Nm
+scans each input
+.Ar file
+for lines that match any of a set of patterns specified literally in
+.Ar prog
+or in one or more files
+specified as
+.Fl f Ar filename .
+With each pattern
+there can be an associated action that will be performed
+when a line of a
+.Ar file
+matches the pattern.
+Each line is matched against the
+pattern portion of every pattern-action statement;
+the associated action is performed for each matched pattern.
+The file name
+.Ar -
+means the standard input.
+Any
+.Ar file
+of the form
+.Ar var=value
+is treated as an assignment, not a filename,
+and is executed at the time it would have been opened if it were a filename.
+.Pp
+The options are as follows:
+.Bl -tag -width indent
+.It Fl d Ns Op Ar N
+Set debug level to specified number
+.Ar N .
+If the number is omitted, debug level is set to 1.
+.It Fl f Ar filename
+Read the AWK program source from specified file
+.Ar filename ,
+instead of the first command line argument.
+Multiple
+.Fl f
+options may be specified.
+.It Fl F Ar fs
+Set the input field separator
+.Va FS
+to the regular expression
+.Ar fs .
+.It Fl mr Ar NNN , Fl mf Ar NNN
+Obsolete, no longer needed options.
+Set limit on maximum record or
+fields number.
+.It Fl safe
+Potentially unsafe functions such as
+.Fn system
+make the program abort (with a warning message).
+.It Fl v Ar var Ns = Ns Ar value
+Assign the value
+.Ar value
+to the variable
+.Va var
+before
+.Ar prog
+is executed.
+Any number of
+.Fl v
+options may be present.
+.It Fl V
+Print
+.Nm
+version on standard output and exit.
+.El
+.Pp
+An input line is normally made up of fields separated by white space,
+or by regular expression
+.Va FS .
+The fields are denoted
+.Va $1 ,
+.Va $2 ,
+\&..., while
+.Va $0
+refers to the entire line.
+If
+.Va FS
+is null, the input line is split into one field per character.
+.Pp
+A pattern-action statement has the form
+.Lp
+.Dl pattern \&{ action \&}
+.Lp
+A missing \&{ action \&}
+means print the line;
+a missing pattern always matches.
+Pattern-action statements are separated by newlines or semicolons.
+.Pp
+An action is a sequence of statements.
+Statements are terminated by
+semicolons, newlines or right braces.
+An empty
+.Ar expression-list
+stands for
+.Va $0 .
+String constants are quoted
+.Em \&"\ \&" ,
+with the usual C escapes recognized within.
+Expressions take on string or numeric values as appropriate,
+and are built using the
+.Sx Operators
+(see next subsection).
+Variables may be scalars, array elements
+(denoted
+.Va x[i] )
+or fields.
+Variables are initialized to the null string.
+Array subscripts may be any string,
+not necessarily numeric;
+this allows for a form of associative memory.
+Multiple subscripts such as
+.Va [i,j,k]
+are permitted; the constituents are concatenated,
+separated by the value of
+.Va SUBSEP .
+.Ss Operators
+.Nm
+operators, in order of decreasing precedence, are:
+.Pp
+.Bl -tag -width ident -compact
+.It Ic (...)
+Grouping
+.It Ic $
+Field reference
+.It Ic ++ --
+Increment and decrement, can be used either as postfix or prefix.
+.It Ic ^
+Exponentiation (the
+.Ic **
+form is also supported, and
+.Ic **=
+for the assignment operator).
+.It + - \&!
+Unary plus, unary minus and logical negation.
+.It * / %
+Multiplication, division and modulus.
+.It + -
+Addition and subtraction.
+.It Ar space
+String concatenation.
+.It Ic \*[Lt] \*[Gt]
+.It Ic \*[Le] \*[Ge]
+.It Ic != ==
+Regular relational operators
+.It Ic ~ !~
