This is needed to make Mercurial read the HGEXTENSIONPATH to detect
|
|
third-party extensions. It is called HGEXTENSIONPATH and not
|
|
HG_EXTENSION_PATH to keep it consistent with other environment variables for
|
|
Mercurial, e.g. HGENCODINGAMBIGUOUS, HGEDITOR ... Hopefully I or someone else
|
|
will get this into Mercurial proper.
