=================== Imposm Packaging Script ============================

This script creates binary packages for Imposm for Linux.
It installs and builds all dependencies, compiles the master
branch of this local repository and creates a .tar.gz with
the imposm3 binary and all 3rd party dependencies.

This script is made for Debian 10. The resulting binaries
should be compatible with all more recent Linux distribution.

'Vagrantfile' defines a working Debian VM that will call this script
during the provision phase. Please install Vagrant and Virtualbox first:
https://www.vagrantup.com/

To start the VM and the packaging:
    $ vagrant up --provision

The resulting .tar.gz should appear in dist/

To build another package, e.g. after you commited new changes:
    $ vagrant provision
or
    $ vagrant ssh
    % bash /vagrant/packaging.sh

You can specify a revision or branch by setting the REVISION
environment. REVISION defaults to the master branch:

    $ REVISION=mybranch vagrant provision

To shutdown the VM:
    $ vagrant halt

To remove the VM:
    $ vagrant destroy
