# Mod history: 2009-05-10 SN (Sergio Navarro). Started adapting
|
|
|
|
|
# from the Luminary131/ file of the same
|
|
|
|
|
# name, using Luminary099 page images.
|
|
|
|
|
# 2009-06-05 RSB Fixed a type.

# 2011-01-06 JL Fixed pseudo-label indentation.

# This source code has been transcribed or otherwise adapted from
|
|
|
|
|
# digitized images of a hardcopy from the MIT Museum. The digitization
|
|
|
|
|
# was performed by Paul Fjeld, and arranged for by Deborah Douglas of
|
|
|
|
|
# the Museum. Many thanks to both. The images (with suitable reduction
|
|
|
|
|
# in storage size and consequent reduction in image quality as well) are
|
|
|
|
|
# available online at www.ibiblio.org/apollo. If for some reason you
|
|
|
|
|
# find that the images are illegible, contact me at info@sandroid.org
|

# about getting access to the (much) higher-quality images which Paul
|
|
|
|
|
# actually created.
