I spend a lot of time reading man pages. Normally, the system pager less is fine for this. Occasionally, they're big enough or important enough that I want to keep them open in a window and read them at leisure. For those cases, I made a 2-line shell script pdfman.sh that runs man to generate postscript and presents the formatted output through preview.
Here is the script:
#!/bin/sh ps=`mktemp -t manpageXXXX`.ps man -t $@ > "$ps" open "$ps"
