+# This script generates these config files:

+#   Integration.uproject
+#   Integration.code-workspace
+#
+# Unreal needs "Integration.uproject".  This config file tells
+# UnrealBuildTool what version of the unreal engine to link this game
+# with.  It also specifies a couple of other game-specific configuration
+# settings.  It can't easily be checked into git because it contains
+# a GUID which is specific to your local machine.
+#
+# VSCode needs "Integration.code-workspace," it tells vscode how to
+# compile this game and how to run it under the debugger.  It can't
+# be checked into git because it contains many hardwired
+# paths.
+#
+# We generate Integration.uproject from scratch.  Later, the unreal
+# editor will inject the engine GUID into the file.
+#
+# The UnrealBuildTool which is included with the UnrealEngine can
+# generate a rough draft of Integration.code-workspace.  However, the
+# file it generates is not well-configured for our luprex-related
+# needs.
+#
+# This python script uses UnrealBuildTool to generate a rough draft,
+# then it loads Integration.code-workspace into RAM, edits it in RAM,
+# and writes a new, improved version back out.
