This is an EXPERIMENTAL feature, use with care.

To enable long paths support, one needs to do two things:

- build Mercurial with --long-paths-support option

- change HKLM\SYSTEM\CurrentControlSet\Control\FileSystem\

LongPathsEnabled to have value 1.

it happens because Mercurial uses mt.exe circa 2008, which is not

yet aware of long paths support in the manifest (I think so at least).
|

|
This does not stop mt.exe from embedding/merging the XML properly.
