The pkg_create command is used to create packages that
  will subsequently be fed to one of the package extraction/info utilities. The
  input description and command line arguments for the creation of a package are
  not really meant to be human-generated, though it is easy enough to do so. It
  is more expected that you will use a front-end tool for the job rather than
  muddling through it yourself. Nonetheless, a short description of the input
  syntax is included in this document.
The following command line options are supported:
  - -Bbuild-info-file
- Install the file build-info-file so that users of
      binary packages can see what
      make(1) definitions were used
      to control the build when creating the binary package. This allows various
      build definitions to be retained in a binary package and viewed wherever
      it is installed, using
      pkg_info(1).
- -bbuild-version-file
- Install the file build-version-file so that users of
      binary packages can see what versions of the files used to control the
      build were used when creating the binary package. This allows some
      fine-grained version control information to be retained in a binary
      package and viewed wherever it is installed, using
      pkg_info(1).
- -Ccpkgs
- Set the initial package conflict list to cpkgs. This
      is assumed to be a whitespace separated list of package names and is meant
      as a convenient shorthand for specifying multiple
      @pkgcfldirectives in the packing list (see
      PACKING LIST DETAILS section below).
- -c[-]desc
- Fetch package (one line description) from file desc
      or, if preceded by -, the argument itself. This
      string should also give some idea of which version of the product (if any)
      the package represents.
- -Ddisplayfile
- Display the file after installing the package. Useful for things like
      legal notices on almost-free software, etc.
- -d[-]desc
- Fetch long description for package from file desc
      or, if preceded by -, the argument itself.
- -Fcompression
- Use compression as compression algorithm. This
      overrides the heuristic to guess the compression type from the output
      name. Currently supported values are bzip2, gzip, none and xz.
- -fpacklist
- Fetch (packing list) for package from the file
      packlist or stdinif
      packlist is a-(dash).
- -ggroup
- Make group the default group ownership instead of
      extracting it from the file system.
- -Irealprefix
- Provide the real prefix, as opposed to the staging prefix, for use in
      staged installations of packages.
- -iiscript
- Set iscript to be the install procedure for the
      package. This can be any executable program (or shell script). It will be
      invoked automatically when the package is later installed.
- -Kpkg_dbdir
- Override the value of the PKG_DBDIRconfiguration
      option with the value pkg_dbdir.
- -kdscript
- Set dscript to be the de-install procedure for the
      package. This can be any executable program (or shell script). It will be
      invoked automatically when the package is later (if ever)
    de-installed.
- -l
- Check that any symbolic links which are to be placed in the package are
      relative to the current prefix. This means using
      unlink(2) and
      symlink(2) to remove and
      re-link any symbolic links which are targeted at full path names.
- -npreserve-file
- The file is used to denote that the package should not be deleted. This is
      intended for use where the deletion of packages may present a bootstrap
      problem.
- -O
- Go into a (packing list only) mode. This is used to do (fake pkg_add)
      operations when a package is installed. In such cases, it is necessary to
      know what the final, adjusted packing list will look like.
- -Pdpkgs
- Set the initial package dependency list to dpkgs.
      This is assumed to be a whitespace separated list of package names and is
      meant as a convenient shorthand for specifying multiple
      @pkgdepdirectives in the packing list (see
      PACKING LIST DETAILS section below). In addition, the exact versions of
      the packages referred to in the dpkgs list will be
      added to the packing list in the form of@blddepdirectives.
- -Tbuildpkgs
- The exact versions of the packages referred to in the
      buildpkgs list will be added to the packing list in
      the form of @blddepdirectives. This directives
      are stored after those created by the-Poption.
      buildpkgs is assumed to be a whitespace separated
      list of package names.
- -pprefix
- Set prefix as the initial directory (base) to start
      from in selecting files for the package.
- -Ssize-all-file
- Store the given file for later querying with the
      pkg_info(1)
      -Sflag. The file is expected to contain the size
      (in bytes) of all files of this package plus any required packages added
      up and stored as a ASCII string, terminated by a newline.
- -ssize-pkg-file
- Store the given file for later querying with the
      pkg_info(1)
      -sflag. The file is expected to contain the size
      (in bytes) of all files of this package added up and stored as a ASCII
      string, terminated by a newline.
- -ttemplate
- Use template as the input to
      mktemp(3). By default, this
      is the string /tmp/instmp.XXXXXX, but it may be
      necessary to override it in the situation where space in your
      /tmp directory is limited. Be sure to leave some
      number of ‘X’ characters for
      mktemp(3) to fill in with a
      unique ID.
- -uowner
- Make owner the default owner instead of extracting
      it from the file system.
- -V
- Print version number and exit.
- -v
- Turn on verbose output.
The (packing list) format (see-f) is fairly simple,
  being nothing more than a single column of filenames to include in the
  package. However, since absolute pathnames are generally a bad idea for a
  package that could be installed potentially anywhere, there is another method
  of specifying where things are supposed to go and, optionally, what ownership
  and mode information they should be installed with. This is done by embedding
  specialized command sequences in the packing list. Briefly described, these
  sequences are:
  - @cwddirectory
- Set the internal directory pointer to point to
      directory. All subsequent filenames will be assumed
      relative to this directory. Note: @cdis also an
      alias for this command.
- @srcdirectory
- This command is supported for compatibility only. It was formerly used to
      override @cwdduring package creation.
- @execcommand
- Execute command as part of the unpacking process. If
      command contains any of the following sequences
      somewhere in it, they will be expanded inline. For the following examples,
      assume that @cwdis set to
      /usr/local and the last extracted file was
      bin/emacs.
      - %F
- Expands to the last filename extracted (as specified), in the example
          case bin/emacs
- %D
- Expand to the current directory prefix, as set with
          @cwd, in the example case
          /usr/local.
- %B
- Expand to the (basename) of the fully qualified filename, that is the
          current directory prefix, plus the last filespec, minus the trailing
          filename. In the example case, that would be
          /usr/local/bin.
- %f
- Expand to the (filename) part of the fully qualified name, or the
          converse of %B, being in the example case,
          emacs.
 
- @unexeccommand
- Execute command as part of the deinstallation
      process. Expansion of special %sequences is the
      same as for@exec. This command is not executed
      during the package add, as@execis, but rather
      when the package is deleted. This is useful for deleting links and other
      ancillary files that were created as a result of adding the package, but
      not directly known to the package's table of contents (and hence not
      automatically removable). The advantage of using@unexecover a deinstallation script is that you
      can use the (special sequence expansion) to get at files regardless of
      where they've been potentially redirected (see-p).
- @modemode
- Set default permission for all subsequently extracted files to
      mode. Format is the same as that used by the
      chmodcommand (well, considering that it's later
      handed off to it, that's no surprise). Use without an arg to set back to
      default (extraction) permissions.
- @optionoption
- Set internal package options, the only currently supported one being
      preserve, which tells pkg_add to move any existing
      files out of the way, preserving the previous contents (which are also
      resurrected on pkg_delete, so caveat emptor).
- @owneruser
- Set default ownership for all subsequently extracted files to
      user. Use without an arg to set back to default
      (extraction) ownership.
- @groupgroup
- Set default group ownership for all subsequently extracted files to
      group. Use without an arg to set back to default
      (extraction) group ownership.
- 
    string
- Embed a comment in the packing list. Useful in trying to document some
      particularly hairy sequence that may trip someone up later.
- @ignore
- Used internally to tell extraction to ignore the next file (don't copy it
      anywhere), as it's used for some special purpose.
- @namename
- Set the name of the package. This is mandatory and is usually put at the
      top. This name is potentially different than the name of the file it came
      in, and is used when keeping track of the package for later
      deinstallation. Note that pkg_createwill derive
      this field from the pkg-name and add it
      automatically if none is given.
- @pkgdirname
- Declare directory name as managed. If it does not
      exist at installation time, it is created. If this directory is no longer
      referenced by packages and the last file or directory in it is deleted,
      the directory is removed as well.
- @dirrmname
- This command is supported for compatibility only. If directory
      name exists, it will be deleted at deinstall
    time.
- @displayname
- Declare name as the file to be displayed at
      install time (see -Dabove).
- @pkgdeppkgname
- Declare a dependency on the pkgname package. The
      pkgname package must be installed before this
      package may be installed, and this package must be deinstalled before the
      pkgname package is deinstalled. Multiple
      @pkgdepdirectives may be used if the package
      depends on multiple other packages.
- @blddeppkgname
- Declare that this package was built with the exact version of
      pkgname (since the @pkgdepdirective may contain wildcards or relational package version
      information).
- @pkgcflpkgcflname
- Declare a conflict with the pkgcflname package, as
      the two packages contain references to the same files, and so cannot
      co-exist on the same system.
Thepkg_create command first appeared in
  FreeBSD.
