 * big spell checking patch -- slif@bellsouth.net
 *
 * Revision 1.4  2003/02/13 07:05:27  oetiker
 * Find attached the patch I promised to send to you. Please note that there
 * are three new source files (src/rrd_is_thread_safe.h, src/rrd_thread_safe.c
 * and src/rrd_not_thread_safe.c) and the introduction of librrd_th. This
 * library is identical to librrd, but it contains support code for per-thread
 * global variables currently used for error information only. This is similar
 * to how errno per-thread variables are implemented.  librrd_th must be linked
 * alongside of libpthred
 *
 * There is also a new file "THREADS", holding some documentation.
 *
 * -- Peter Stamfest <peter@stamfest.at>
 *
 * Revision 1.3  2002/02/01 20:34:49  oetiker
 * fixed version number and date/time
 *
 * Revision 1.2  2001/03/10 23:54:39  oetiker
 * Support for COMPUTE data sources (CDEF data sources). Removes the RPN
 * parser and calculator from rrd_graph and puts then in a new file,
 * rrd_rpncalc.c. Changes to core files rrd_create and rrd_update. Some
 * clean-up of aberrant behavior stuff, including a bug fix.
 * Documentation update (rrdcreate.pod, rrdupdate.pod). Change xml format.
