* Syntax: splitpdf filein n rootname
*
* n = number of output files
* rootname: the root of the output file names, which are in the format:
* [rootname]_001.pdf
* [rootname]_002.pdf
* ...
*
* Notes:
* (1) This calls mutool to split the input file into a set of %n files
* mutool clean -g -g filein fileout page-range
* (2) It attempts to put the same number of pages in each file.
* (3) If the number %n of output files specified is greater than
* 'npages', the number of pages in the input pdf file, this will
* write 'npages' files, with one page per file.
