## Detailed Description

Basic classes for Ipe.

Some very basic type definitions, streams, lexical analysis, and XML parsing.

All parts of Ipe make use of the STL. The C++ I/O streams library is not used, as Ipelib doesn't do much I/O. Ipe objects support internalization and externalization through an abstract interface based on ipe::Stream's.

Clients of Ipelib can use any I/O library that implements this interface. Ipe simply uses `cstdio`.
