### TIPS & EXAMPLES
* use grex full to run the full FRB detection pipeline
* use grex cands to run the pipeline through heimdall, dumping candidates
* use grex filterbank to run just T0 to fill a filterbank file
* use grex none to run just T0 with no exfil (only talks to Prometheus)
* use grex cleanup to cleanup DADA buffers that were left around from a crash
* use grex check to check if this script is ready to execute and what values the options/flags are
grex check
* use grex env to generate an example .env file
grex env > .env
* use grex update to update to the latest version
grex update
