# fix-chapel-replace-chpl-about.sh — replace dropped `chpl --about` with
# the 2.8-compatible equivalent.
#
# Driven by hypatia WF024 (chapel-replace-chpl-about-with-version recipe).
# Sharp edge #3 in panic-attack wiki Chapel-Metalayer.md: `chpl --about` was
# removed in Chapel 2.8 — workflows that rely on it for diagnostic output
# break silently (no `--about` flag is a no-op + exits 0 on some versions).
#
# Replace with `chpl --version && printchplenv` which gives the same
# information across the 2.7/2.8 split.
#
# Idempotent.
