# Requires ImageMagick


# Converting the source from JPEG to PNG - if necessary
convert my_src_image.jpg my_src_image.png


# Option A
#  - Requires a temporary intermediate file

# C implementation of Levenshtein text distance algorithm, uses RubyInline to call from within Ruby
# Wildly faster than the Text gem's Text::Levenshtein
# Example:

# l = Levenshtein.new
# l.distance 'hello', ' hello'
# => 1

#!/usr/bin/env bash
# Note the use of env. This is because executables may not be placed in the same place on all systems. Notoriously, bsd (and thus mac osx) differs from linux. However, /usr/bin/env always exists in the same place, and it can tell you where other executables are. Thus, the above is good style for portability.
