+// Copyright © 2015,2019,2020,2023 KSLib team 
+// Lic. MIT
+
+// Originally developed by abenkovskii
+
+// The mess below declares a function execute that executes a command from it's string representation.
+// I'm 95% sure there is no easy way to achieve this behavior in the current version of kOS (0.17).
+// All easier solutions I know fail to work as expected in a range of special cases.
+// If you think you know an easy way to implement it there are unit tests
+// in KSLib/unit_tests/lib_exec to test your implementation.
+// See "run is weird" for more detailed information: [link is coming soon (tm)]
+
+// The execute function is now implemented using an incrementing string so that each time the function is called there is a unique file name.
+// This modification was done in kOS version (1.1.9.0) and works as of that version.
+// It should be backwards compatible with earlier versions of kOS but this has not been tested.
+
+// nuggreat's notes about run/runpath as of kOS version (1.1.9.0)
+// When a file is run for the first time it gets stored in memory so that any additional calls to run the given file can be served a lot faster.
+// This means that even if you delete a file and then recreate it with different stuff it that won't update the version kOS is storing as the user has no way to make kOS forget a stored instance of a file.
+// And as files are IDed by there name (and possibly path haven't tested that) if the name doesn't change even if the contents do then kOS will run the version it stored.
+// The version kOS stores only leaves memory when kOS falls back to the terminal level.
+// Thus for a file to be runnable with different internal commands it must have a different name.
+// NOTE: This might change in the future but at least as of kOS version (1.1.9.0) this is the way run appears to work.
