# Purpose:
|
|
# - Reads a set of markdown examples from a hash which has been serialized to disk
|
|
# - Converts each example to static HTML using the `markdown` helper
|
|
# - Writes the HTML for each example to a hash which is serialized to disk
|
|
#
|
|
# It should be invoked via `rails runner` from the Rails root directory.
|
|
# It is intended to be invoked from the `update_example_snapshots.rb` script class.
