PureFTPd Manager

This is for Mac OS X. It's great if you want to do it quickly and skip installing mac ports and configuring txt files and inits. 

When used with 10.7 aka Lion, you have to change the pam file so that system users can log in. After installation:

sudo mv /etc/pam.d/pure-ftpd /etc/pam.d/pure-ftpd.orig
sudo cp /etc/pam.d/ftpd /etc/pam.d/pure-ftpd.orig
