tclcl snapshot

[Yan Yu <yanyu@catarina.usc.edu>]

when I try to make install yesterday's tclcl snapshot, I got the error:

cp libtclcl.a /home/netlab1/yanyu/ns/ns-2/tclcl-1.0b8/lib/libtclcl.a
test -e /home/netlab1/yanyu/ns/ns-2/tclcl-1.0b8/lib/libTcl.a && rm -f 
/home/netlab1/yanyu/ns/ns-2/tclcl-1.0b8/lib/libTcl.a || true
sh: test: argument expected
*** Error code 1 (ignored)

so I change "test -e" to "test -f" in Makefile. Is this what it is 
supposed to mean? ( btw, I could not find "-e" option in "test" manual)

Thanks in advance!
