# This is a build script that creates STK linux package.
#
# To run the script you need debootstrap and schroot packages, and working
# chroot environment.
#
# The build environment can be created using debootstrap:
#
#   debootstrap --arch i386 --components=main \
#               jessie ./chroot-jessie32 http://ftp.debian.org/debian
#
#   debootstrap --arch amd64 --components=main \
#               jessie ./chroot-jessie64 http://ftp.debian.org/debian
#
#
# Here is example configuration for schroot:
# /etc/schroot/chroot.d/chroot-jessie32.conf
#
#   [chroot-jessie32]
#   description=Debian Jessie
#   personality=linux32
#   directory=/path/to/chroot-jessie32
#   root-users=deve
#   type=directory
#   users=deve
#
#
# /etc/schroot/chroot.d/chroot-jessie64.conf
#
#   [chroot-jessie64]
#   description=Debian Jessie 64-bit
#   #personality=linux32
#   directory=/path/to/chroot-jessie64
#   root-users=deve
#   type=directory
#   users=deve
#
#
# Packages that are needed to compile all STK dependencies have to be installed
# manually inside both chroot directories.
