# Create directory structure, download Tigase XMPP Server -dist-max package and unpack it
# At the same time remove setting JAVA_HOME from etc/tigase.conf as variable is already set
# and add additional parameters to GC variable to make Java aware of Docker limits
# Then move content of etc/ directory to etc.orig/ to be able to use volume to host configuration.
# Additionally we are removing docs/ and downloaded package to reduce size.
