Description:

	unixODBC is an Open Source ODBC sub-system and an ODBC SDK
	for Linux, Mac OSX, and UNIX. 
	
License:
	
	All libraries are LGPL Version 2.1
	
	All programs are GPL Version 2.0.

Parts:
	unixODBC includes the following;
	
	- Driver Manager
	- Installer Library and command line tool
	- Command Line Tools to help install a driver and work with SQL
	

How To Start:

	Look for and read README files with extensions of interest. Then
	read the INSTALL file.
	
	You can also jump into the doc directory and browse information 
	there. And do not forget the online stuff.
	
	Some documentation may be a bit out of date the vast majority of
	it should be ok.
	
Config Files:

	The ODBC Installer Library is responsible for reading and writing
	the unixODBC config files. 
	
	The savvy can look at;
	 
	_odbcinst_SystemINI.c
	_odbcinst_UserINI.c
	
	In any case; you can override where unixODBC looks for its system
	config files by setting the ODBCSYSINI environment variable during 
	the use of unixODBC.
