+.Sh NAME
+.Nm xstr
+.Nd "extract strings from C programs to implement shared strings"
+.Sh SYNOPSIS
+.Nm
+.Op Fl cv
+.Op Fl l Ar array
+.Op Fl
+.Op Ar
+.Sh DESCRIPTION
+.Nm
+maintains a file
+.Pa strings
+into which strings in component parts of a large program are hashed.
+These strings are replaced with references to this common area.
+This serves to implement shared constant strings, most useful if they
+are also read-only.
+.Pp
+Available options:
+.Bl -tag -width XXlXarrayXX
+.It Fl
+.Nm
+reads from the standard input.
+.It Fl c
+.Nm
+will extract the strings from the C source
+.Ar file
+or the standard input
+.Pq Fl ,
+replacing
+string references by expressions of the form (\*[Am]xstr[number])
+for some number.
+An appropriate declaration of
+.Nm
+is prepended to the file.
+The resulting C text is placed in the file
+.Pa x.c ,
+to then be compiled.
+The strings from this file are placed in the
+.Pa strings
+data base if they are not there already.
+Repeated strings and strings which are suffixes of existing strings
+do not cause changes to the data base.
+.It Fl l Ar array
+Specify the named array in program references to abstracted
+strings.
+The default array name is xstr.
+.It Fl v
+Be verbose.
+.El
+.Pp
+After all components of a large program have been compiled, a file
+.Pa xs.c
+declaring the common
+.Nm
+space can be created by a command of the form:
+.Pp
+.Dl $ xstr
+.Pp
+The file
+.Pa xs.c
+should then be compiled and loaded with the rest
+of the program.
+If possible, the array can be made read-only (shared) saving
+space and swap overhead.
+.Pp
+.Nm
+can also be used on a single file.
+The following command creates files
+.Pa x.c
+and
+.Pa xs.c
+as before, without using or affecting any
+.Pa strings
+file in the same directory:
+.Pp
+.Dl $ xstr name
+.Pp
+It may be useful to run
+.Nm
+after the C preprocessor if any macro definitions yield strings
+or if there is conditional code which contains strings
+which may not, in fact, be needed.
+An appropriate command sequence for running
+.Nm
+after the C preprocessor is:
+.Pp
+.Bd -literal -offset indent
+$ cc \-E name.c | xstr \-c \-
+$ cc \-c x.c
+$ mv x.o name.o
+.Ed
+.Pp
+.Nm
+does not touch the file
+.Pa strings
+unless new items are added, thus
+.Xr make 1
+can avoid remaking
+.Pa xs.o
+unless truly necessary.
+.Sh FILES
+.Bl -tag -width /tmp/xsxx* -compact
+.It Pa strings
+Data base of strings
+.It Pa x.c
+Massaged C source
+.It Pa xs.c
+C source for definition of array `xstr'
+.It Pa /tmp/xs*
+Temp file when `xstr name' doesn't touch
+.Pa strings
+.El
+.Sh SEE ALSO
+.Xr mkstr 1
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Bx 3.0 .
+.Sh BUGS
+If a string is a suffix of another string in the data base,
+but the shorter string is seen first by
+.Nm
+both strings will be placed in the data base, when just
+placing the longer one there will do.
+.Pp
+.Nm
+does not parse the file properly so it does not know not to process:
+.Bd -literal
+ char var[] = "const";
+.Ed
+into:
+.Bd -literal
+ char var[] = (\*[Am]xstr[N]);
+.Ed
+.Pp
+These must be changed manually into an appropriate initialization for
+the string, or use the following ugly hack.
+.Pp
+Also,
+.Nm
+cannot initialize structures and unions that contain strings.
+Those can be fixed by changing from:
+.Bd -literal
+ struct foo {
+ int i;
+ char buf[10];
+ } = {
+ 1, "foo"
+ };
+.Ed
+to:
+.Bd -literal
+ struct foo {
+ int i;
+ char buf[10];
+ } = {
+ 1, { 'f', 'o', 'o', '\e0' }
+ };
+.Ed
+.Pp
+The real problem in both cases above is that the compiler knows the size
+of the literal constant so that it can perform the initialization required,
+but when
+.Nm
+changes the literal string to a pointer reference, the size information is
+lost.
+It would require a real parser to do this right, so the obvious solution is
+to fix the program manually to compile, or even better rely on the compiler
+and the linker to merge strings appropriately.
+.Pp
+Finally,
+.Nm
+is not very useful these days because most of the string merging is done
+automatically by the compiler and the linker, provided that the strings
+are identical and read-only.
