# count_labels: Print a summary of how many times a particular label

# To find the sizes of the pools assigned to a board:

$USAGE -p | -b | -v | -l <label>
$USAGE -h
Standard input to this command is the output of some variant of
'atest host list'. The command line option selects a particular
category of label to be counted:
-p: Count \"pool:\" label values.
-b: Count \"board:\" label values.
-v: Count \"variant:\" label values.
-l <label>: Count values of labels named \"<label>:\"
Exactly one label selection option must be supplied; there is no
default, and multiple options aren't allowed.
The comand reports the counts of the various values of the
selected label.
Example:
\$ atest host list -b board:daisy_skate | count_labels -p
