apt - Advanced Package Tool
APT is a management system for software packages. For normal day to day
package management there are several frontends available, such as
aptitude(8) for the command line or synaptic(8) for the X Window
System. Some options are only implemented in apt-get(8) though.
apt-cache(8), apt-get(8), apt.conf(5), sources.list(5),
apt returns zero on normal operation, decimal 100 on error.
This manpage isn't even started.
