+#### Line number counting
 
 Regarding line number counting (`-[xX]`), note that gztool's index counts last line in uncompressed data even if the last char isn't a newline char - whilst `wc` command will not count it in this case!. Nonetheless, line counting when extracting data with `-[bLtT]` does follow `wc` convention - this is in order to not obtain different (+/-1) results reading `gztool` output info and `wc` counts.
