+std::strings are awkward. Also, you can never trust the standard library. std::vector<bool> anyone?
+
+This is a mutable ASCII/UTF-8 string class with every convenience feature I can think of added in, portability shims for MSVC, and support for converting to/from unicode codepoints.
+
+Depends on amsarrays from amsmathutil25 for handling arrays of strings.
 
-Rearrange my C++ project template in an attempt to harmonize everything and modernize my build scripts.
