Probably I will never have a VPS so this wiki will live in a git
repository only. To make the article urls work properly so the
wiki can be browsed, I removed the leading `/`.
For the record, this is what I used (sed could have done the job too):
```
find articles -type f -name '*.md' -exec \
perl -pi -e 's/\[([^]]+)\]\(\/([a-zA-Z0-9\/_.-]+)\)/\[\1\]\(\2\)/g' {} \;
````
