This code provides support for complex numbers in Lua using the functions
available in C99.

To try the library, just edit Makefile to reflect your installation of Lua and
then run make. This will build the library and run a simple test. For detailed
installation instructions, see
	http://www.tecgraf.puc-rio.br/~lhf/ftp/lua/install.html

There is no manual: see the summary below and a C99 reference manual, e.g.
http://www.dinkumware.com/manuals/default.aspx?manual=compleat&page=complex2.html

Read also test.lua, which shows the library in action.

This code is hereby placed in the public domain.

Please send comments, suggestions, and bug reports to lhf@tecgraf.puc-rio.br .
