@ -3501,6 +3501,13 @@ example(zargs -e.. -- **/*(.) .. ls -l)
This is a good choice in that example because no plain file can be named
`tt(..)', but the best end-marker depends on the circumstances.
The options tt(-i), tt(-I), tt(-l), tt(-L), and tt(-n) differ slightly
from their usage in tt(xargs). There are no input lines for tt(zargs) to
count, so tt(-l) and tt(-L) count through the var(input) list, and tt(-n)
counts the number of arguments passed to each execution of var(command),
em(including) any var(arg) list. Also, any time tt(-i) or tt(-I) is used,
each var(input) is processed separately as if by `tt(-L) tt(1)'.
For details of the other tt(zargs) options, see zmanref(xargs) (but note
the difference in function between tt(zargs) and tt(xargs)) or run
tt(zargs) with the tt(-)tt(-help) option.
