# This file will be overwritten during an FHEM update and all

# To avoid this, we recommend following procedure:
#
# 1. Create your own file 99_myUtils.pm from the template below,
# e.g. with FHEMWEB, Edit files, Editing 99_Utils.pm, and saving it as
# 99_myUtils.pm
# 2. Put this file inside the ./FHEM directory
# 3. Put your own functions into this new file

use warnings;
use POSIX;

myUtils_Initialize($$)
