"The fact that the easiest way to copy a program is from one neighbor to another, the fact that a program has both source code and object code which are distinct, and the fact that a program is used rather than read and enjoyed, combine to create a situation in which a person who enforces a copyright is harming society as a whole both materially and spiritually." Richard Stallman

• getting decent looking pdf from TeX: \usepackage{pslatex} in the preamble
• get the acrobat reader for linux: this is vastly superior to xpdf both because the user interface is useful and because of the tools for working with pdf files it provides
• run /usr/local/Acrobat4/bin/acroread --help from the command line to get information about how you can use acroread
• script to concatenate pdf files $1, $2 to $3

/usr/local/Acrobat4/bin/acroread -toPostScript -pairs $1 /tmp/$1.ps
/usr/local/Acrobat4/bin/acroread -toPostScript -pairs $2 /tmp/$2.ps
a2ps --columns=1 -o /tmp/$1.both.ps /tmp/$1.ps /tmp/$2.ps
ps2pdf /tmp/$1.both.ps $3
rm -f /tmp/$1.ps
rm -f /tmp/$2.ps
rm -f /tmp/$1.both.ps

• acroread can also be used to extract pages from a pdf file by extracting them to ps, then converting back to pdf
• or if you have ghostscript you might try (thanks to Pete Johnson who tried this and says it works.)
