# this code is duplicated in installation.py because execute.py file is
# copied into /usr/bin directory in .spec. To handle it we can:
# 1. Create package in /opt/alt, but:
# 1.1 In plesk extension case python38 is installed after this code
# 2. Save code in var/etc directories and use symlinks technique, but:
# 2.1 Again, plesk extension
# 2.2 Symlinks may be disabled in the system
# (so endusers will not be able to use extension)
# 2.3 This directories are not intended for such usage
# (var is even deletable)
# 3. Store this files in new place in each extension
# 3.1 There are 4 extensions * 2 os types
# also present in installation.py
