"""jc - JSON CLI output utility `rpm -qai` command output parser
Works with `rpm -qi [package]` or `rpm -qai`.
The `build_epoch` calculated timestamp field is naive (i.e. based on the local time of the system the parser is run on)
The `build_epoch_utc` calculated timestamp field is timezone-aware and is only available if the timezone field is UTC.
Usage (cli):
$ rpm -qai | jc --rpm_qai
or
$ jc rpm -qai
Usage (module):
import jc.parsers.rpm_qai
result = jc.parsers.rpm_qai.parse(rpm_qai_command_output)
Compatibility:
'linux'
Examples:
$ rpm_qai | jc --rpm_qai -p
