# This streamlet counts lines of code of given files. It calls the tool cloc.

# Specific attributes can be selected using options – e.g. --option 'attribute' 'code'

# or --option "attribute" "total" (sum of code, comment and blank lines, hidden by default).

#

# Optional prefix can be added to attribute names: --option 'prefix' 'my_prefix_'
