+# Note: limit for recursive symlinks on linux:
+# http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/fs/namei.c?id=refs/heads/master#l808
+# This limits recursive symlink follows to 8,
+# while limiting consecutive symlinks to 40.
+#
+# When resolving and displaying information about symlinks, no check is made
+# that the displayed information does make any sense on your OS.
+# We leave that decission to the user.
+#
+# The zstat module is used to detect symlink loops. zstat is available since zsh4.
+# With an older zsh you will need to abort with <C-c> in that case.
+# When a symlink loop is detected, a warning ist printed and further processing is stopped.
+#
+# Module zstat is loaded by default in grml zshrc, no extra action needed for that.
+#
+# Known bugs:
+# If you happen to come across a symlink that points to a destination on another partition
+# with the same inode number, that will be marked as symlink loop though it is not.
+# Two hints for this situation:
+# I) Play lottery the same day, as you seem to be rather lucky right now.
+# II) Send patches.
+#
+# return status:
+# 0 upon success
+# 1 file/dir not accesible
