+This is simplified faster version with much more lower lines of code of
+https://github.com/Tarrasch/zsh-autoenv.
+
+Possibly harmful modifications:
+
+* Removed debugging messages. Only the fact that autoenv file is sourced
+* Removed autoenv_*_path helpers -- "path" array is already simple and
+ convenient to work with
+* Removed workaround function when zsh/stat module is lacked
+* Removed autoenv_source_parent() -- useless for me
+* Removed autoenv-edit() -- too trivial task
+* No testing provided
+
+Optimizations:
+
+* Removed old checksum format version support
+* Less subshell invocations -- only cksum is left
+* Heavily simplified and faster _autoenv_get_file_upwards() -- original
+ was compatible with an old zsh versions
+* varstash library is loaded without checking if autoenv needs it -- it
+ is faster to load it anyway, than to invoke grep every time
+* ctime is used instead of mtime, without size storage (unnecessary)
