4 Packaging System ¶

A package is a directory formed of several files, from these files, only build, checksums, and version files are mandatory.

This section talks about files that are interpreted specially by the package manager. Any other file can be added to the package directory at the discretion of the package maintainer. Everything in the package directory will also be added to the package database that is located on ‘/var/db/cpt/installed’. These can be patches, configuration files, etc.

Below is a table that provides a small summary for each file, see the relevant section to learn detailed information on each of them.

File	Language	Executable	Mandatory

checksums	generated by ‘cpt-checksum’	no	no
meta	key-value pairs as in RFC8221	no	no2
