-// This adds the `dlls` directory to the path so the dlls can be found. How
-// MO is able to find dlls in there is a bit convoluted:
-//
-// Dependencies on DLLs can be baked into an executable by passing a
-// `manifestdependency` option to the linker. This can be done on the command
-// line or with a pragma. Typically, the dependency will not be a hardcoded
-// filename, but an assembly name, such as Microsoft.Windows.Common-Controls.
-//
-// When Windows loads the exe, it will look for this assembly in a variety of
-// places, such as in the WinSxS folder, but also in the program's folder. It
-// will look for `assemblyname.dll` or `assemblyname/assemblyname.dll` and try
-// to load that.
-//
-// If these files don't exist, then the loader gets creative and looks for
-// `assemblyname.manifest` and `assemblyname/assemblyname.manifest`. A manifest
-// file is just an XML file that can contain a list of DLLs to load for this
-// assembly.
-//
-// In MO's case, there's a `pragma` at the beginning of this file which adds
-// `dlls` as an "assembly" dependency. This is a bit of a hack to just force
-// the loader to eventually find `dlls/dlls.manifest`, which contains the list
-// of all the DLLs MO requires to load.
-//
-// This file was handwritten in `modorganizer/src/dlls.manifest.qt5` and
-// is copied and renamed in CMakeLists.txt into `bin/dlls/dlls.manifest`. Note
-// that the useless and incorrect .qt5 extension is removed.

+// This adds the `dlls` directory to the path so the dlls can be found. How
+// MO is able to find dlls in there is a bit convoluted:
+//
+// Dependencies on DLLs can be baked into an executable by passing a
+// `manifestdependency` option to the linker. This can be done on the command
+// line or with a pragma. Typically, the dependency will not be a hardcoded
+// filename, but an assembly name, such as Microsoft.Windows.Common-Controls.
+//
+// When Windows loads the exe, it will look for this assembly in a variety of
+// places, such as in the WinSxS folder, but also in the program's folder. It
+// will look for `assemblyname.dll` or `assemblyname/assemblyname.dll` and try
+// to load that.
+//
+// If these files don't exist, then the loader gets creative and looks for
+// `assemblyname.manifest` and `assemblyname/assemblyname.manifest`. A manifest
+// file is just an XML file that can contain a list of DLLs to load for this
+// assembly.
+//
+// In MO's case, there's a `pragma` at the beginning of this file which adds
+// `dlls` as an "assembly" dependency. This is a bit of a hack to just force
+// the loader to eventually find `dlls/dlls.manifest`, which contains the list
+// of all the DLLs MO requires to load.
+//
+// This file was handwritten in `modorganizer/src/dlls.manifest.qt5` and
+// is copied and renamed in CMakeLists.txt into `bin/dlls/dlls.manifest`. Note
+// that the useless and incorrect .qt5 extension is removed.
