 ## Usage tips:
+- don't put any destructive actions in your Custom Data Extractors scrips
+- try to keep as little custom data as possible, to speed up scanning and searching records and keep record files small
+- if general purpose and generally available tools produce too much and not needed text data, write a wrapper script (*.sh, *bat) executing specific tool and post-process retrieved data. Wrapper can also help when the tool expects more variable parameters or in an unusual order
