# Those <censored> mIRC'ers have all those irritating system info "remotes" to
# brag about their system.
# Now, it's up to Irssi users to brag about their pentium 75's and 2 Gio harddisks.
# :)

# Differences to Juerd-only-version:
# -YASFU units (Mio, Gio) - http://snull.cjb.net/?yasfu
# -Free memory and free swap are displayed (previously only total swap/mem)
# -Reorganized and tuned output
# -Displays length of your virtual penis (this is quite tricky, so you might want to disable it by commenting)
# -Doesn't display info on nfs/smbfs/none-type mounts (edit script if you want those)

# Vpenis is not 100% compatible with Cras' vpenis.sh - I have fixed some bugs:
# -More network filesystems excluded (originally only NFS was excluded)
# -Total amount of memory counts (not the used amount, as before)

# Changelog 2.10 -> 2.20: memory/swap info is displayed now (it was broken previously) and code is properly indented
