clop ls                      # run 'ls --help' and count its options
clop ls cp mv                # several programs, plus a combined SUMMARY
clop --csv ls cp mv          # machine-readable CSV
clop --list ls               # also print the option names that were counted
ls --help | clop -           # read help text from standard input
clop -f captured-help.txt    # read help text from a saved file

What it reports

For each program, clop records the program's version and prints five numbers:

Field	Meaning
`version`	The program's version, detected from `program --version`.
`total options`	Number of distinct options (one per option line in the help).
`with aliases`	Options that have more than one spelling, e.g. `-a` / `--all`.
`without aliases`	Options that have exactly one spelling.
`short option names`	Number of short forms counted, e.g. `-a`, `-1`.
`long option names`	Number of long forms counted, e.g. `--all`, `--block-size`.

Output formats

default: a human-readable report
--csv: name,version,total,with,without,short,long
--tsv: the same columns, tab-separated
--no-header: omit the header row in --csv / --tsv
--list: additionally list the option names that were counted

Labelling sources

When you read from a file or standard input, there is no program name or version for clop to discover. You can supply them yourself:

clop --name busybox -f busybox.help                 # label the source
clop --name tar --prog-version 1.35 -f tar.help     # also record a version
