Import mksandbox-1.0 as pkgtools/mksandbox.

A small shell script to set up a sandbox (usually for a pkgsrc bulk
build), using null mounts.

The file lived in pkgsrc/mk/bulk/mksandbox, but is worthy of its own
package IMHO. New: with manpage.

+.Op Fl Fl src Ns = Ns Ar srcdir
+.Op Fl Fl verbose
+.Op Fl Fl without-x
+.Op Fl Fl xsrc Ns = Ns Ar xsrcdir
+.Ar sandbox-dir
+.Sh DESCRIPTION
+.Nm
+is a small shell script to set up a sandbox (usually for a pkgsrc bulk
+build), using null mounts.
+The sandbox is set up for the target directory
+.Ar sandbox-dir .
+.Pp
+The supported options are:
+.Bl -tag -width "Xpkgsrc=dirXXX"
+.It Fl Fl pkgsrc Ns = Ns Ar dir
+Look for the pkgsrc files in
+.Ar dir
+instead of the default
+.Pa /usr/pkgsrc .
+.It Fl Fl src Ns = Ns Ar srcdir
+Look for the
+.Nx
+src files in
+.Ar dir
+instead of the default
+.Pa /usr/src
+(only needed for some packages that compile kernel modules).
+.It Fl Fl verbose
+More verbose output.
+.It Fl Fl without-x
+Do not include X files in the sandbox.
+.It Fl Fl xsrc Ns = Ns Ar xsrcdir
+Look for the
+.Nx
+xsrc files in
+.Ar dir
+instead of the default
+.Pa /usr/src
+(only needed for some packages).
