This runtime-compiled helper executable is then used to extract + various bits and peices from Cabal\'s on disk state (dist/setup-config) + written by it's configure command. + + In addition to this the wrapper executable also supports installing any + version of Cabal from hackage in case it cannot be found in any available + package database. The wrapper installs these instances of the Cabal library + into a private package database so as to not interfere with the user's + packages. + + Furthermore the wrapper supports one special case namely reading a state + file for Cabal itself. This is needed as Cabal compiles it's Setup.hs using + itself and not using any version of Cabal installed in any package database. + + @cabal-helper@ can compile with @Cabal >= 1.14@ but requires @Cabal >= 1.16@ + at runtime. + </longdescription> +</pkgmetadata> |
