# This is the main file for the user preferences conversion system.
# There are two subsidiary files:
-# prefs2prefs_lfuns.py
-# prefs2prefs_prefs.py
+# prefs2prefs_lfuns.py
+# prefs2prefs_prefs.py
# The former is used to convert bind and ui files; the latter, to convert
-# the preferences file.
-#
-# I've organized it this way because, in many ways, converting bind and ui
-# files lfuns) and converting the preferences file are the same task. It's
-# very line-by-line, unlike lyx2lyx and layout2layout, where changes can be
-# more "global". So we read the file, line by line, and give a bunch of
-# converter functions a chance to see if they want to modify that line.
-
-# The converter functions are all in the subsidiary files. They take a line
-# as argument and return a list: (Bool, NewLine), where the Bool says if
-# we've modified anything and the NewLine is the new line, if so, which will
-# be used to replace the old line.
-
-# The format of the existing files is format 0, as of 2.0.alpha6. We'll
-# introduce new format numbers as we proceed, just as with layout2layout.
-# These will be different for the bind and ui files and for the preferences
-# file.
