This directory contains the files needed for building pyqtdeploy bundle.

Now you can manually build the bundle for linux. Assuming your sysroot
dir will be in SYSROOTDIR (you'll need about 6GB free space there for
building Qt) and sources - in SOURCEDIR, the build steps are following:

1. cd $SOURCEDIR && exec /path/to/PyBitmessage/packages/pyqtdeploy/download.sh
1. cd /path/to/PyBitmessage/packages/pyqtdeploy
1. pyqtdeploy-sysroot --source-dir $SOURCEDIR --sysroot $SYSROOTDIR --target linux-64 --plugin-dir plugins sysroot.json
1. virtualenv depends
1. source depends/bin/activate
1. pip install enum34 msgpack qtpy stem
1. deactivate
1. pyqtdeploy-build --sysroot $SYSROOTDIR --target linux-64 pybitmessage.pdy
1. cd build-linux-64
1. mv resources/src resources/pybitmessage
1. sed -i "s|src/|pybitmessage/|g" resources/pyqtdeploy.qrc
1. $SYSROOTDIR/host/bin/qmake
1. make

The resulting PyBitmessage binary may require some shared libraries,
particularly openssl.

There is also a possible issue with pyexpat related to `sqlite3`:
