I'm wondering what the proper value of $TERM would be for screen running in a terminal which initially has its $TERM variable equal to "xterm-256color". Once I launch screen, $TERM becomes "screen", which seems to lack many capabilities, notably: applications don't consider it to be capable of displaying 256 colors.
Searching the web brought up several potential values that $TERM should have in this situation, including "screen-256color" and "screen.xterm-256color", but I'm not sure what's the proper answer.
