%description
This tool dynamically optimizes energy consumption on HPC systems by
adjusting the CPU max frequency according to electricity price, carbon
intensity (CI) and/or CPU/inlet temperature. The active regulators are
selected via configuration (price/CO2, temperature, or both).

Designed to be run periodically (e.g., via cron every few minutes under
root), it classifies the current conditions, applies a frequency policy,
and records each evaluation to an SQLite database and a JSON state file.

# The setuptools console_scripts launcher resolves its entry point at runtime
# via importlib.metadata. On Python 3.9 that reader does not reliably parse the
# legacy .egg-info this build produces, so the generated /usr/bin/hpc-eff fails
# with StopIteration. Replace it with a thin wrapper that invokes the module
# directly -- importing hpc_eff.main needs no metadata lookup.
#
# TODO: the proper fix is a wheel-based pip install (modern .dist-info reads
# reliably on every Python). It needs pip + wheel present at build time, which
# this box lacks, so do it on a hermetic builder and drop this wrapper.
