This directory contains common-use classes, most of which are not specific to GSM.

Vector		A vector class (NOT std::vector<>) that supports
		aliased subvectors.  Not resizable.
BitVector	Bit-indexable vectors based on Vector.
Interthread	A set of C++ wrappers for pthread facilities.
Sockets		A set of C++ wrappers for Unix sockets.
Timeval		A C++ wraper for struct timeval.
LinkLists	Classes for simple linked lists of pointers.

Do "make tests" to build a series of unit tests for these classes.
