### Changes
I tried to find out which would be the main_repo and it is important to
notice that many are not hosted on github or neither using a git repo
(using svn for example).
Besides that, I was also not able to find out the main repo for the
following projects:
| **file** | **comment** |
|------------------------|-----------------------------------------------------------------------------------|
| lzo/project.yaml | |
| qcms/project.yaml | |
| bzip2/project.yaml | |
| dlplibs/project.yaml | |
| freeimage/project.yaml | hosted on csv
https://sourceforge.net/p/freeimage/code/ |
| xerces-c/project.yaml | |
| xpdf/project.yaml | |
| lzma/project.yaml | at source forge but no code section found
https://sourceforge.net/projects/p7zip/ |
Another case that I was not sure about which url do add on the
`qubes-os/project.yaml`. Its homepage is related to the entire org.
