Want to make a nifty brochure using LaTeX and the leaflet package? Of course you do. Find that it's overwriting each individual panel of the brochure on top of each other? I did. The fix for me was to change fold.sh to this:
pstops -pletter "6:1(0,0)+3(0,-0.6666667h)+2(0,-0.3333334h),4(0,0in)+5(0,-0.3333334h)+0(0,-0.6666667h)" $*
Magic, but it worked for me. Took about an hour of cursing to get the values right - and now, you can fix it too! No need to thank me. (Note - possibly useful on a Gentoo Linux using LaTeX and the leaflet package. Probably not useful otherwise.)
