-This makes it possible to take backup of nnml/nnfolder servers/groups
-separately of .newsrc.eld, while preserving marks. It also makes it
-possible to share articles and marks between users (without sharing
-the .newsrc.eld file) within e.g. a department. It works by storing
-the marks stored in .newsrc.eld in a per-group file ".marks" (for
-nnml) and "groupname.mrk" (for nnfolder, named "groupname"). If the
-nnml/nnfolder is moved to another machine, Gnus will automatically use
-the .marks or .mrk file instead of the information in .newsrc.eld.
-The new server variables `nnml-marks-is-evil' and
-`nnfolder-marks-is-evil' can be used to disable this feature.
