Further infos:

• solution complete, i.e., able to compute all solutions

findAllVersions :: GlobalCache -> String -> Bool -> [Package]   

Finds all versions of a package in the global package cache.

findNewestVersion :: GlobalCache -> String -> Maybe Package   

Finds the newest version of a package.

findVersion :: GlobalCache -> String -> (Int, Int, Int, Maybe String) -> Maybe Package   

Finds a specific version of a package.

installedPackageDir :: Config -> Package -> String   

The directory of a package in the global package cache. Does not check whether the package is actually installed!

packageInstalled :: Config -> Package -> IO Bool   

Checks whether a package is installed in the global cache.

copyPackage :: Config -> Package -> String -> ErrorLogger ()   

Copy a package version to a directory.

acquireAndInstallPackage :: Config -> Package -> ErrorLogger ()   

Acquires a package, either from the global tar file repository or from the source specified in its specification, and installs it to the global package cache.

acquireAndInstallPackageFromSource :: Config -> Package -> ErrorLogger ()   

Acquires a package from the source specified in its specification and installs it to the global package cache.

installFromZip :: Config -> String -> ErrorLogger ()   

Installs a package from a ZIP file to the global package cache.

installMissingDependencies :: Config -> GlobalCache -> [Package] -> ErrorLogger ()   

Installs a package's missing dependencies.

missingPackages :: GlobalCache -> [Package] -> [Package]   

Filters a list of packages to the ones not installed in the global package cache.

checkoutPackage :: Config -> Package -> String -> ErrorLogger ()   

Checkout a package from the global package cache.

uninstallPackage :: Config -> String -> (Int, Int, Int, Maybe String) -> ErrorLogger ()   

Removes a package from the global package cache.

tryFindPackage :: GlobalCache -> String -> (Int, Int, Int, Maybe String) -> ErrorLogger Package   

Tries to find a package in the global package cache.

readGlobalCache :: Config -> Repository -> ErrorLogger GlobalCache   

Reads the global package cache.

readInstalledPackagesFromDir :: Repository -> String -> ErrorLogger (Either String GlobalCache)   

Tries to read package specifications from a GC directory structure. If some GC package directory has the same name as a package from the repository index, the package specification from the repository is used, otherwise (this case should not occur) the package specification stored in the directory is read. This should result in faster GC loading.
