+pkg_comp is a small utility designed to build packages inside a
+clean chroot tree.
+
+Some ideas about what to use it for (taken from manpage):
+* Build packages for other system versions. For example, build
+  packages for NetBSD 1.5 while you are running NetBSD current.
+* Build packages using different options than your current system
+  like changing the threading library, COPTS, placement of
+  configuration files, etc.
+* Debug the build process of a package, checking if buildlinks
+  work properly.
+* Avoid autoconf's side effects by keeping a separate chroot for
+  each project, like one for GNOME2 and another one for KDE3.

+.Sh NAME
+.Nm pkg_comp
+.Nd build packages inside a chroot
+.Sh SYNOPSIS
+.Nm
+.Op Ar -c conf_file
+.Ar target
+.Op Ar pkg_name ...
+.Sh DESCRIPTION
+.Nm
+is a tool that makes easy the compilation of packages inside a clean
+chroot environment. This allows an easy tracking of exact dependancies
+and the correct behaviour of a package in a fresh system installation.
+.Pp
+The behavior of
+.Nm
+is controlled trought a small configuration file and a target (keep
+reading to learn more). The configuration file tells
+.Nm
+how to configure the new chroot environment, and the target specifies
+which action to take.
+.Pp
+.Ss What to use it for?
+You can use
+.Nm
+to achieve many goals when buildling packages. Here are some ideas:
+.Bl -bullet -item
+.It
+Build packages for other system versions. For example, build packages for
+.Nx 1.5
+while you are running
+.Nx current .
+.It
+Build packages using different
+.Pa mk.conf
+options than your current system, like changing the threading library,
+.Sy COPTS ,
+placement of configuration files, etc.
+.It
+Debug the build process of a package, checking if buildlinks work
+properly.
+.It
+Avoid autoconf's side effects by keeping a separate chroot for each
+project, like one for GNOME2 and another one for KDE3.
+.El
+.Pp
+.Sh CONTROL DIRECTORY
+.Nm
+needs to store several information when it is running. Instead of
+using normal system trees, it uses a special directory inside the
+chroot to avoid polluting the system. It stores there scripts, object
+files, built packages, etc.  This directory is located by default in
+.Pa $DESTDIR/pkg_comp .
+.Pp
+.Sh CONFIGURATION
+With
+.Nm
+you can maintain several configuration files so you can work with
+different chroot jails easily. To make this easy, configuration files
+are stored inside
+.Pa $HOME/pkg_comp ,
+followed by the configuration file name and the .conf suffix. The default
+configuration file is
+.Pa $HOME/pkg_comp/default.conf ,
+and is always used if you do not specify another one.
+.Pp
+Configuration files are simple shell scripts that define
+variables. The default values shown here are those written in the
+template when issuing a maketemplate.
+.Bl -tag -width indent
+.It BUILD_TARGET
+The target to use when buildling packages. It can contain any target
+supported by the pkgsrc system, but reasonable values are:
+.Ql install
+and
+.Ql package .
+Defaults to
+.Ql package .
+.It COPYROOTCFG
+If set to
+.Ql yes ,
+all configuration files (not directories) that reside inside
+.Pa /root
+are copied to
+.Sy $DESTDIR/root .
+Defaults to
+.Ql no .
+.It DESTDIR
+The chroot jail directory. Defaults to
+.Pa /var/chroot/pkg_comp/default .
+.It DISTRIBDIR
+This is the directory which holds
+.Nb
+binary sets and X sets. Its structure is the same as official release
+distributions, that is, tgz files must reside inside
+.Pa $DISTRIBDIR/binary/sets .
+Defaults to
+.Pa /var/pub/NetBSD .
+.It INSTALL_PACKAGES
+A list of packages to automatically install after the
+.Sy makeroot
+and after installing
+.Sy MAKE_PACKAGES .
+Each name must be the full package name, including the tgz suffix. Packages
+are searched inside
+.Pa $REAL_PACKAGES/All .
+Defaults to nothing.
+.It MAKE_PACKAGES
+A list of packages to automatically build after the
+.Sy makeroot
+target. A package is in the form section/name, like
+misc/colorls. Defaults to nothing.
+.It PTHREAD_TYPE
+The threading type to use when building packages. Defaults to
+.Ql pth .
+.It ROOTSHELL
+The shell of the root user. Defaults to
+.Pa /bin/sh .
+.It SETS
+A list of binary sets to be extracted inside
+.Sy DESTDIR .
+Defaults to
+.Ql base.tgz comp.tgz etc.tgz text.tgz .
+.It SETS_X11
+A list of binary sets of the X Window system. This has the same behavior
+as
+.Sy SETS .
+If this variable is empty, no X Window is configured inside the chroot
+jail and no other X variables take effect. Default to
+.Ql xbase.tgz xcomp.tgz xcontrib.tgz xfont.tgz xmisc.tgz xserver.tgz .
+.It USE_XF86_4
+If set to
+.Ql yes ,
+sets specified in SETS_X11 contain X Window version 4. Has no effect if
+X is unconfigured. Defaults to
+.Ql yes .
+.It USE_XPKGWEDGE
+If set to
+.Ql yes ,
+you want xpkgwedge to be compiled and installed automatically inside the
+chroot. This takes care of setting up
+.Pa /etc/profile
+and
+.Pa /etc/csh.login
+for xpkgwedge to work. Has no effect if X is unconfiguerd. Defaults to
+.Ql yes .
+.El
+.Ss Mounted filesystems
+In order to avoid duplicating huge system trees,
+.Nm
+takes advantadge of filesystem layers. By default, it uses
+.Xr mount_null 8 ,
+which duplicates a filesystem tree into another directory; although
+you may want to use
+.Xr mount_union 8 ,
+or even
+.Xr mount_overlay 8 .
+If the
+content of these variables is empty, that filesystem is not mounted.
+.Pp
+You can control which layer to use and which options you want with
+special configuration options, as explained below.
+.Pp
+These filesystems are mounted before entering the chroot and unmounted
+after exiting. In order to know if filesystems are mounted or not, the
+program uses a temporary file, called
+.Pa $DESTDIR/pkg_comp/tmp/mount.stat ,
+which controls the number of
+.Nm
+processes using the chroot environment. If some of them crashes
+unexpectedly and you notice it does not try to unmount the
+filesystems, this status file may get out of sync. Be sure to check if
+NO filesystems are mounted when issuing a
+.Sy removeroot .
+.Bl -tag -width indent
+.It REAL_DISTFILES
+Specifies where distfiles reside in the real system. Defaults to
+.Pa /usr/pkgsrc/distfiles .
+.It REAL_DISTFILES_OPTS
+Mount options. Defaults to
+.Sy -t null -o ro .
+.It REAL_PACKAGES
+Specifies where to build binary packages. This variable is specially useful.
+Defaults to
+.Pa /usr/pkgsrc/packages .
+.It REAL_PACKAGES_OPTS
+Mount options. Defaults to
+.Sy -t null -o ro .
+.It REAL_PKGSRC
+The pkgsrc tree. This can be useful if you want to use several pkgsrc trees
+independantly. Defaults to
+.Pa /usr/pkgsrc .
+.It REAL_PKGSRC_OPTS
+Mount options. Defaults to
+.Sy -t null -o rw .
+.It REAL_SRC
+The src system tree. Usually useless, but may be needed by some packages,
+like sysutils/aperture. Defaults to
+.Pa /usr/src .
+.It REAL_SRC_OPTS
+Mount options. Defaults to
+.Sy -t null -o rw .
+.El
+.Pp
+.Sh TARGETS
+A target specifies what
+.Nm
+should do (as in make). The following list describes all supported targets,
+in the logical order you should call them.
+.Bl -tag -width indent
+.It maketemplate
+Create a sample
+.Ar conf_file .
+You should edit it after the creation as you will probably want to change
+the default configuration, specially paths.
+.It makeroot
+Create the chroot environment, based on the specs of the configuration file.
+This step is required before trying any other, except maketemplate .
+.It build
+Builds the specified packages inside the chroot. You need to pass their
+names as relative paths inside pkgsrc, like
+.Pa pkgtools/pkg_comp .
+.It install
+Install the specified binary packages into the chroot. You must specify
+the full name of the package and they must be reside inside
+.Sy REAL_PACKAGES .
+.It chroot
+Enters the chroot environment.
+.It removepkgs
+Remove all the packages in the chroot environment. It starts deleting
+packages with
+.Xr pkg_delete 1
+and then cleans the package tree and the database. This will rebuild
+.Sy MAKE_PACKAGES ,
+reinstall
+.Sy INSTALL_PACKAGES
+and xpkgwedge if they are specified in the configuration file.
+.It removeroot
+Remove the entire chroot tree. You should do it with this target because it
+will take care to umount needed mount points.
+.It auto
+This executes several targets automatically, setting
+.Sy BUILD_TARGET
+to package. The order is: makeroot, build and removeroot. This is
+useful to create binary packages of several pkgsrc and their
+dependancies automatically. For this to be useful, you need to set
+.Sy REAL_PACKAGES
+and use
+.Sy MAKE_PACKAGES
+or pass package names trought the command line.
+.El
+.Pp
+.Sh NOTES
+This program uses nullfs to create virtual copies of real trees inside the
+chroot environment.

+.Sh AUTHORS
+Julio Merino <jmmv@hispabsd.org>

+.Xr packages 7 ,
+.Xr mount_null 8 .
+.Sh BUGS
+Probably many, specially error checking.
