+* Until weekend (21-22. July) I'll try to fix all errors above. (done)
* From 22.July until 29. July I'll try to set up a first security check
My plans are two parts of a security check:
* One with an array of blacklisted regular expression. (This would blacklist all the well known and easy to fetch things like \include {/path/to/something} and things like closing the math formula environment ($$).
