Update to 2.02

2.02: more progress on portability; introduced the beginnings of a suite
 of tests; improvements in the --keepinfo functionality, and to the
 treatment of file permissions (thanks to Marco Pessotto for these).
 [2010-04-14]

2.01: fixed a silly bug (thoughtless use of "test -a" in a couple of
 places) which seriously affected portability. [2010-04-13]

2.00: a major re-design. This is not completely backward-compatible with
 previous versions of the pdfnup, pdfjoin and pdf90 scripts. The
 differences in interface are few, though.

 In addition, various reported bugs have been fixed - many thanks to all
 those kind people who reported them (too numerous to list here!)

1.21: bug fixes, including security issues (many thanks to Eduard Bloch,
 Robert Buchholz and Martin Vaeth for helpful reports on vulnerabilities
 and for kindly contributing patches); the scripts now call for /bin/bash
 as interpreter; availability of mktemp is now also assumed; the
 Mac OS X droplets now look for pdflatex at (by default)
 /usr/texbin/pdflatex [2009-01-19]
