Download an evaluation copy of T-Rex (t_rex.zip, 331K, version 1.50). The evaluation period is 90 days and the unit is fully functional. You just can't distribute programs that use it.
If you like it, get the source
now
from Albert's Ambry (//www.alberts.com). (This is just
the source. The support files are in the evaluation copy so you
need that too.)
You can find the latest version of the
evaluation copy on the Delphi forum, Library 23/Third-party
Products, filename t_rex.zip, and you can license it via
the SWREG service.
