OpenGEODE
=========

OpenGEODE is a tiny open-source SDL editor that is developed for
the purpose of providing an easy to use and free state machine editor and
Ada code generator to the TASTE toolchain from the European Space Agency,
running in combination with ESA's ASN.1 "Space Certifiable" ASN.1 compiler.

SDL is the Specification and Description Language (Z100 standard from ITU-T).

This is NOT related to the graphical Simple DirectMedia Layer libraries!

Visit http://sdl-forum.org for more information about SDL.

91
92
Make sure all dependencies are installed.

93
If you see a certificate error, you may need to run the following commands:
94
95
96
97
98
99

```bash
$ echo -n | openssl s_client -connect gitrepos.estec.esa.int:443 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > gitrepos.cert
$ sudo cp gitrepos.cert /usr/local/share/ca-certificates/gitrepos.crt
$ sudo update-ca-certificate
```
100

101
Then you can get the software with git:
