# Old, needs updating after move from wiki/
# Run the commands in pages' examples and see if they succeed.
# Usage:
# 1. extract a page's example files to a subdirectory named like the page (without the .md)
# 2. run this script with zero or more page arguments (with or without the .md).
# Eg: ./test   # runs all tests found
# Note current limitations:
# - all and only lines in pages beginning with "$ " are considered commands
# - only extracted files are tested, not what's actually in the pages
# - only commands' exit status is tested, not their output

echo "Testing exit status (not output) and extracted files (not page content)"
