+# Force - makes sure there is exactly 1 space/brace/newline/etc,
+# behaves like Add in some contexts
+# Remove - removes space/brace/newline/etc
+#
+#
+# - Token(s) can be treated as specific type(s) with the 'set' option:
+# `set tokenType tokenString [tokenString...]`
+#
+# Example:
+# `set BOOL __AND__ __OR__`
+#
+# tokenTypes are defined in src/token_enum.h, use them without the
+# 'CT_' prefix: 'CT_BOOL' => 'BOOL'
+#
+#
+# - Token(s) can be treated as type(s) with the 'type' option.
+# `type tokenString [tokenString...]`
+#
+# Example:
+# `type int c_uint_8 Rectangle`
+#
+# This can also be achieved with `set TYPE int c_uint_8 Rectangle`
+#
+#
+# To embed whitespace in tokenStrings use the '\' escape character, or quote
+# the tokenStrings. These quotes are supported: "'`
+#
+#
+# - Support for the auto detection of languages through the file ending can be
+# added using the 'file_ext' command.
+# `file_ext langType langString [langString..]`
+#
+# Example:
+# `file_ext CPP .ch .cxx .cpp.in`
+#
+# langTypes are defined in uncrusify_types.h in the lang_flag_e enum, use
+# them without the 'LANG_' prefix: 'LANG_CPP' => 'CPP'
+#
+#
+# - Custom macro-based indentation can be set up using 'macro-open',
+# 'macro-else' and 'macro-close'.
+# `(macro-open | macro-else | macro-close) tokenString`
+#
+# Example:
+# `macro-open BEGIN_TEMPLATE_MESSAGE_MAP`
+# `macro-open BEGIN_MESSAGE_MAP`
+# `macro-close END_MESSAGE_MAP`
