# camel.sh -- Print greeting messages in camel-case (e.g., "HeLlO,
# WoRlD!"). The output is printed out one character per line. This
# might not have sense but it helps to describe how execution of
# sibling modules work. Notice that, when printing final output,
# punctuation marks doesn't count for formating.
