+QMake Lexer
+
+There are 3 types of identifiers recognized by this lexer:
+-id_simple: examples of such identifiers are qmake variables and scoped variables
+at the left of the operator in assignments (like "SOURCES" in "SOURCES+=foo.cpp goo.cpp");
+-id_list: those are "value list identifiers" at the right side in assignments
+(like "foo.cpp goo.cpp" in "SOURCES+=foo.cpp goo.cpp");
+-id_args: function arguments recognized as one identifier
+(example: ""${QMAKE_FILE} is intended only for Windows!""
+in "!win32-*:!wince-*:error("${QMAKE_FILE} is intended only for Windows!")" statements).
+.
+
+To recognize those identifiers two additional start conditions are used: list and funcargs.
+
+@note "Not" operator (!) is recognized as a part of an identifier. Linefeeds passed to
+the parser as NEWLINE tokens to preserve file structure but whitespaces are stripped
+so no indentation is preserved by this lexer (and parser).
+
+To debug this lexer, put the line below into the next flex file section.
