Capri (abbreviation of CAbal PRIvate) is a wrapper program on top of cabal-install to operate it in project-private mode. In this mode, there is no global or user package databases; only one package database is defined, private to the project, located under the root directory of a project.
Capri is mainly intended for use with projects organized as Cabal packages targeting executables rather than just libraries.
