-/**
- * What is this?
- *
- * "This" is a preprocessor that makes an attempt to convert fully valid C++11 source code
- * in utf-8 into something consumable by certain compilers (Solaris, xlC)
- * which aren't quite standards compliant.
- *
- * - u"<unicode>" or u'<unicode>' gets converted to u"\uNNNN" or u'\uNNNN'
- * - u8"<unicode>" gets converted to "\xAA\xBB\xCC\xDD" etc.
- *   (some compilers do not support the u8 prefix correctly.)
- * - if the system is EBCDIC-based, that is used to correct the input characters.
- *
- * Usage:
- *   escapesrc infile.cpp outfile.cpp
- * Normally this is invoked by the build stage, with a rule such as:
- *
- * _%.cpp: $(srcdir)/%.cpp
- *       @$(BINDIR)/escapesrc$(EXEEXT) $< $@
- * %.o: _%.cpp
- *       $(COMPILE.cc) ... $@ $<
- *
- * In the Makefiles, SKIP_ESCAPING=YES is used to prevent escapesrc.cpp
- * from being itself escaped.
