using makecron

["Benner, Michael L" <michael.benner@twc.state.tx.us>]

I'm trying to use the makecron function of WebGlimpse to set up a nightly
reindexing of my website.
I've run the makecron script (./makecron) but it only returns the following
response without prompting
for input before exiting:

Making reindexing script /usr/local/webglimpse/wgreindex

I've searched the Webglimpse site but didn't find any information about
makecron.  I've also looked at
the makecron code which suggests that user input is needed to properly set
up the cron task.
Has anyone used this script to set up automated indexing of a site?  Any
tips on how to use it properly?

Thanks,
