-## A few notes about includes and excludes:
-## 1. include, exclude and vsinclude statements support globbing with '*'
-## 2. Symlinks are not dereferenced. Moreover, an include line whose path
-##    contains, at any level, a symlink to a directory, will only have the
-##    symlink backed-up, not the target directory's content. Yes, you have to
-##    dereference yourself the symlinks, or to use 'mount --bind' instead.
-##    Example: let's say /home is a symlink to /mnt/crypt/home ; the following
-##    line will only backup a "/home" symlink ; neither /home/user nor
-##    /home/user/Mail will be backed-up :
-##      include = /home/user/Mail
-##    A workaround is to 'mount --bind /mnt/crypt/home /home' ; another one is to
-##    write :
-##      include = /mnt/crypt/home/user/Mail
-## 3. All the excludes come after all the includes. The order is not otherwise
-##    taken into account.

-## vsinclude = <path>
-## ...
-## Any path specified in vsinclude is added to the include list for each vserver
-## listed in vsnames (or all if vsnames = all, which is the default).
-##
-## For example, vsinclude = /home will backup the /home directory in every
-## vserver listed in vsnames. If you have 'vsnames = foo bar baz', this
-## vsinclude will add to the include list /vservers/foo/home, /vservers/bar/home
