Similar think was discussed for mass delinearization in the
http://sourceforge.net/mailarchive/message.php?msg_id=BAY106-W5219A792D82C6E60E3BD3E9CE60%40phx.gbl
thread.

Attached, you can find script which defines two functions (
__mass_merge - for low-level usage - meaning that direct usage of pdf
instances
mass_merge - for high-level usage - meaining that filenames are used for
output and input docuemnts)
In theory, it can be used for your purpose, but I had hard times how to
use it without gui :(
When you place it into the ~/.pdfedit/scripts directory, you can use it
from gui - justcall
mass_merge("output_file", ["input1" "input2" ... ["inputN"]])
where output_file is existing pdf document which will contain all pages
(including those it contains originaly) from all input documents (note
that they are defined as array, so they have to be enclosed in `[' `]'
and elements are separated by space).
Note that the script is just example without proper error handling and
all paths should be absolute (otherwise you would need to play with the
script a bit).
pdfedit has -console and -run parameters which should work also without
GUI, but there some issues we have to deal with before this script can
be useable from them.
I hope that at least this will help a bit.
Just a hint for more automatic handling:
You can also generate input array from directory regexp, but it needs
some more tweaking:
(quick kick off)
Dir d = new Dir(PATH);
var l = d.entryList('*.pdf'); // l contains array compatible list of all
// pdf documents in the PATH (but it
// contains only names and doesn't
// contain path - so you need to expand
// each element with PATH
nass_merge("output.pdf", l);
So put all your documents to the PATH and this should work for you.
