[p4] Scripting label creation

[Yamuna Ramasubramaniyan]

Hello,

I am trying to script label creation to go along with our daily builds
(I am aware that labeling is wasteful and there are better methods, but
that's for phase II of our build system).  I can't make sense of the p4
label command though.  I'm trying to avoid cat file | p4 label -i, but I
can't seem to find any way around it.

Here's what I have:
P4 label -o TemplateLabel newLabel > temp.file
editlabelDescription(temp.file)    --- I need to store a description of
the label
cat temp.file | p4 label -i

I'm sure there are more elegant solutions, could someone please
enlighten me?  

Thanks,
Yamuna
