.SH NAME
opkhelper \- opkg build helper tools

.SH DESCRIPTION
opkhelper is a set of programs to assist in building binary packages installable
by the lightweight package manager
.BR opkg .
These tools are inspired by debhelper, a similar set of programs written
primarily by Joey Hess for Debian.
.sp
opkhelper 2.0.x is designed to build source packages that comply with draft
version 2.0 of the source package format at
.IR http://specs.os.pehjota.net/source-package-format-2.0.html .

.SH MAINTAINER AND PACKAGE INTERFACES
opkhelper exposes various interfaces to users building packages and to packages
themselves.  Users generally just call
.B opkbuild(1)
to begin building packages.  The
.I build
file of a package generally calls a number of opkhelper tools to help it manage
and pack data and control files for packages.  Additionally,
.B opkbuild(1)
documents the build environment by setting environment variables that are
available to the
.I build
file and other opkhelper tools.

.SH ENVIRONMENT VARIABLES
opkbuild makes available to package
.IR config and build
files and other opkhelper tools a number of environment variables that describe
the packages being built, the build and host systems, and the toolchain to be
used.  The difference between "build" and "host" systems follows the convention
set by GNU Autoconf.  The build system is the one on which software is built.
The host system is the one on which software is to be run.  For more information, see
.IR https://www.gnu.org/software/autoconf/manual/autoconf.html#Specifying-Targe\
t-Triplets .
