- This file initializes the system and loads the font loader. To
- minimize potential conflicts between other packages and the code
- imported from \CONTEXT, several precautions are in order. Some of
- the functionality that the font loader expects to be present, like
- raw access to callbacks, are assumed to have been disabled by
- \identifier{luatexbase} when this file is processed. In some cases
- it is possible to trick it by putting dummies into place and
- restoring the behavior from \identifier{luatexbase} after
- initilization. Other cases such as attribute allocation require
- that we hook the functionality from \identifier{luatexbase} into
- locations where they normally wouldn’t be.
-
- Anyways we can import the code base without modifications, which is
- due mostly to the extra effort by Hans Hagen to make \LUATEX-Fonts
- self-contained and encapsulate it, and especially due to his
- willingness to incorporate our suggestions.

+
+ This file initializes the system and loads the font loader. To
+ minimize potential conflicts between other packages and the code
+ imported from \CONTEXT, several precautions are in order. Some of
+ the functionality that the font loader expects to be present, like
+ raw access to callbacks, are assumed to have been disabled by
+ \identifier{luatexbase} when this file is processed. In some cases
+ it is possible to trick it by putting dummies into place and
+ restoring the behavior from \identifier{luatexbase} after
+ initilization. Other cases such as attribute allocation require
+ that we hook the functionality from \identifier{luatexbase} into
+ locations where they normally wouldn’t be.
+
+ Anyways we can import the code base without modifications, which is
+ due mostly to the extra effort by Hans Hagen to make \LUATEX-Fonts
+ self-contained and encapsulate it, and especially due to his
+ willingness to incorporate our suggestions.
