+# BIG FAT WARNING
+# 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
