combine

This very simple utility combines multiple PDF files into a single PDF.

It is used as follows:

pygacity combine <output_file.pdf> <input_file1.pdf> <input_file2.pdf> ...

where <output_file.pdf> is the name of the combined output PDF file, and <input_file1.pdf>, <input_file2.pdf>, etc. are the names of the input PDF files to be combined in the specified order.
