This page returns error:
https://sourceforge.net/p/parapascal/code/Btw, it is frontend problem, mercurial repository is working fine from console, both pushing and pulling.
See for yourselves:
hg clone http://hg.code.sf.net/p/parapascal/code parapascal
Repo appears empty now, although a checkout shows many files.
The originally referenced repos (in ticket body, and first comments) look fine to me now.
