 HISTORY OF THE SOFTWARE\

+\f1\b0 \ulnone \
 Python was created in the early 1990s by Guido van Rossum at Stichting Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands as a successor of a language called ABC. Guido remains Python's principal author, although it includes many contributions from others.\
 \
 In 1995, Guido continued his work on Python at the Corporation for National Research Initiatives (CNRI, see http://www.cnri.reston.va.us) in Reston, Virginia where he released several versions of the software.\

 Thanks to the many outside volunteers who have worked under Guido's direction to make these releases possible.\
