Working with the edi Source Code

Instead of installing edi from the ppa you can also work directly with the source code.

Clone the source code:

git clone https://github.com/lueschem/edi.git

Change into the edi subfolder:
```
cd edi
```

Install various packages that are required for the development of this project:

sudo apt install -y git-buildpackage dh-make equivs && sudo mk-build-deps -i debian/control

Build the edi Debian package (just to verify that everything works):
```
debuild -us -uc
```
Make the development setup convenient by adding some environment variables (they are only valid for the current shell):
```
source local_setup
```
Verify that the source code version of edi is being used:
```
which edi
edi version
```
