-USAGE = """generate_resource_whitelist.py [-h] [-i INPUT] [-o OUTPUT]
-
-INPUT specifies a file containing existing resource IDs that should be
-whitelisted, where each line of INPUT contains a single resource ID.
-
-Creates a resource whitelist by collecting existing resource IDs that are part
-of unknown pragma warnings and adds additional arch specfic resource IDs.
-
-This script is used to find the resources that are actually compiled in Chrome
-in order to only include the needed strings/images in Chrome PAK files.
-These resource IDs show up in the build output after building Chrome with
-gn variable enable_resource_whitelist_generation set to true.
-This causes the compiler to print out an UnknownPragma message every time a
-resource ID is used.
-
-E.g. foo.cc:22:0: warning: ignoring #pragma whitelisted_resource_12345
-[-Wunknown-pragmas]
-
-On Windows, the message is simply a message via __pragma(message(...)).
