-# list of loaded scripts keyed by their package names
-# The package names are generated from the filename of the script using
-# the file2pkg() function.
-# The values of this hash are hash references with the following keys:
-#   filename
-#     The full path to the script.
-#   gui_entry
-#     This is hexchat_plugin pointer that is used to remove the script from
-#     Plugins and Scripts window when a script is unloaded. This has also
-#     been converted with the PTR2IV() macro.
-#   hooks
-#     This is an array of hooks that are associated with this script.
-#     These are pointers that have been converted with the PTR2IV() macro.
-#   inner_packages
-#     Other packages that are defined in a script. This is not recommended
-#     partly because these will also get removed when a script is unloaded.
-#   loaded_at
-#     A timestamp of when the script was loaded. The value is whatever
-#     Time::HiRes::time() returns. This is used to retain load order when
-#     using the RELOADALL command.
-#   shutdown
-#     This is either a code ref or undef. It will be executed just before a
-#     script is unloaded.
