.Sh NAME
.Nm cdpack
.Nd produce multi-CD binary package images
.Sh SYNOPSIS
.Nm ""
.Op -ac | -ec
.Op -af | -ef
.Op -l logfile
.Op -dnRvV
.Op -x common_directory
.Op -X extras_directory
.Ar packages_directory
.Ar cd_image_directory
.Sh DESCRIPTION
The
.Nm
utility produces ISO 9660 image files for
a multiple CD-ROM collection of binary packages.
.Pp
The
.Nm
utility extracts the dependency information from the binary
packages in the directory
.Ar packages_directory
specified on the command line.  The dependency information is
used to determine which packages are placed on which CD.  The
directory
.Ar cd_image_directory
is used as a staging area and the final ISO 9660 images are left in
that directory.  A file,
.Ar .index ,
which lists the contents of each CD will be left in the root
directory of each CD image.
.Bl -tag -width "-x directory "
.It Fl ac
Include binary packages marked as NO_BIN_ON_CDROM on the CD set.
The default is to omit any
packages which were marked as NO_BIN_ON_CDROM.  This option should
only be used when making a CD set for personal use and not for
distribution unless you are sure you have not violated any licenses.
.It Fl af
Include binary packages marked as NO_BIN_ON_FTP on the CD set.
This option is enabled by default.
.It Fl d
Enable debugging by not deleting temporary files at the end of the
run.  These files are left in TMPDIR.
.It Fl ec
Exclude packages marked as NO_BIN_ON_CDROM from the CD set.  This is
the default.
.It Fl ef
Exclude packages marked as NO_BIN_ON_FTP from the CD set.  The default
is to allow packages which are NO_BIN_ON_FTP.
.It Fl l Ar logfile
Log the output of mkisofs -v -v to the file
.Ar logfile .
.It Fl n
Do not duplicate packages in order to prevent inter-CD dependencies.
The default without the
.Fl n
option will place a package and all of its dependencies on the same
CD.  If a particular package is also required by pacakges on other
CD's, it will be placed there as well.
When the
.Fl n
option is used packages are not duplicated.  This results in slightly
smaller ISO 9660 images.
.Nm
places packages which are lower in the dependency tree on lower
numbered CD-ROM's and packages which are higher on the higher numbered
CD-ROM's.  In this fashion, a package on CD number n
will have all of its dependencies on CD numbers 1 through n
.It Fl R
Generate a file,
.Ar README.txt ,
which will be placed in the root directory of each CD image.  This
README file contains a small amount of information about the contents
of the CD set.
.It Fl v
Be verbose.  Currently does not change things much.
.It Fl V
Print the program version number and exit.
.It Fl x Ar directory
Includes the contents of
.Ar directory
on each CD.  This is useful for README files, etc., which you want
to be present on each CD in the set.
.It Fl X Ar directory
Includes the contents of
.Ar directory
on the last CD in the set.  This is useful for adding
a pkgsrc.tar.gz tarball, i.e. a file which does not
need to be on each CD.
.El
.Pp
The
.Nm
utility exits 0 on success, and >0 if an error occurs.
.Sh ENVIRONMENT
.Nm
uses the fillowing environment variables if set.
.Bl -tag -width "TMPDIR"
.It Ev TMPDIR
Directory for holding temporary files during the image creation.
Defaults to
.Dq Li /tmp .
.El
.Sh EXAMPLES
This example takes all of the binary packages found in
/usr/pkgsrc/packages/All and creates cd images in
/u2/cdimages/cd{1,2,...}.iso.  The directories
/u2/cdimages/cd{1,2,...} are used to create the ISO 9660 layouts.
.D1 cdpack /usr/pkgsrc/packages/All /u2/cdimages
.Pp
To include a common set of files on all CD's, place them in a
directory, /tmp/foo, in this example, and pass in the directory name
with the
.Fl x
option.
.Dl cdpack -x /tmp/foo /usr/pkgsrc/packages/All /u2/cdimages
.Sh SEE ALSO
.Xr mkisofs 1
.Sh HISTORY
The
.Nm
utility first appeared in the
.Nx
packages collection in April, 2001.
.Sh AUTHORS
The
.Nm
utility was written by Dan McMahill (dmcmahill@netbsd.org).  The
idea of duplicating packages to eliminate inter-CD dependencies
came from Todd Vierling (tv@netbsd.org).
