Good Catch!!  I fixed this.  I'll put out a release soon w/ this fix.

Any chance you could edit the real rlib documentation?  rlib/doc 

It's really not that hard.  Try doing to that directory and typing
"make".  If all goes well you will have a pdf manual.  If you might have
to install db2pdf or something.

Yes.  We should add it to the real RLIB manual.

It seems that you didn't copy array.xml and array2.xml into
your /var/www/html/Dev dir.  Among other things these examples show you
how to include other XML files

To do labels I would suggest having a part w/ 2 or 3 columns like:

<pr>
  <pd width='33%'>
    --- Include Report w/ labels here
  </pd>
  <pd width='33%'>
    --- Include Report w/ labels here
  </pd>
  <pd width='33%'>
    --- Include Report w/ labels here
  </pd>
</pr>

The next trick is to query mod 3 or in RLIB suppress based on a mod 3.
So that there will be an even amount of rows

Like (Col 1) <line suppress"iif(r.rowcount%3==0,yes,no)"> ...
Like (Col 2) <line suppress"iif(r.rowcount+1%3==0,yes,no)"> ...
Like (Col 3) <line suppress"iif(r.rowcount+2%3==0,yes,no)"> ...

Also figuring out the amount of white space will trial and error.. when
you are done it would be a nice contribution for the project.
