+# 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,restricted,universe,multiverse \
+#               xenial ./chroot-xenial32 http://archive.ubuntu.com/ubuntu/
+#
+#   debootstrap --arch amd64 --components=main,restricted,universe,multiverse \
+#               xenial ./chroot-xenial64 http://archive.ubuntu.com/ubuntu/
+#
+#
+# Here is example configuration for schroot:
+# /etc/schroot/chroot.d/chroot-xenial32.conf
+#
+#   [chroot-xenial32]
+#   description=Ubuntu Xenial
+#   personality=linux32
+#   directory=/path/to/chroot-xenial32
+#   root-users=deve
+#   type=directory
+#   users=deve
+#
+#
+# /etc/schroot/chroot.d/chroot-xenial64.conf
+#
+#   [chroot-xenial64]
+#   description=Ubuntu Xenial 64-bit
+#   #personality=linux32
+#   directory=/path/to/chroot-xenial64
+#   root-users=deve
+#   type=directory
+#   users=deve
+#
+#
+# And some packages that may be useful (esp. build tools, sdl2 and openal 
+# dependencies)
