# This script is executed by GitHub Actions for every pull request opened.
|
|
# It currently accomplishes the following objectives (for English pages only):
|
|
#
|
|
# 1. Detect pages that were just copied (i.e. cp pages/{common,linux}/7z.md).
|
|
# 2. Detect pages that were added in a platform specific directory although
|
|
# they already exist under 'common'.
|
|
# 3. Detect pages that were added in the 'common' platform although they
|
|
# already exist under a platform specific directory.
|
|
# 4. Detect other miscellaneous anomalies in the pages folder.
|
|
#
|
|
# Results are printed to stdout, logs and errors to stderr.
|
|
#

# NOTE: must be run from the repository root directory to correctly work!
