-- This manages everything to do with where files get installed (though does
-- not get involved with actually doing any installation). It provides an
-- 'InstallDirs' type which is a set of directories for where to install
-- things. It also handles the fact that we use templates in these install
-- dirs. For example most install dirs are relative to some @$prefix@ and by
-- changing the prefix all other dirs still end up changed appropriately. So it
-- provides a 'PathTemplate' type and functions for substituting for these
-- templates.

-- | The installation directories in terms of 'PathTemplate's that contain
-- variables.
--
-- The defaults for most of the directories are relative to each other, in
-- particular they are all relative to a single prefix. This makes it
-- convenient for the user to override the default installation directory
-- by only having to specify --prefix=... rather than overriding each
-- individually. This is done by allowing $-style variables in the dirs.
-- These are expanded by textual substitution (see 'substPathTemplate').
--
-- A few of these installation directories are split into two components, the
-- dir and subdir. The full installation path is formed by combining the two
-- together with @\/@. The reason for this is compatibility with other Unix
-- build systems which also support @--libdir@ and @--datadir@. We would like
-- users to be able to configure @--libdir=\/usr\/lib64@ for example but
-- because by default we want to support installing multiple versions of
-- packages and building the same package for multiple compilers we append the
-- libsubdir to get: @\/usr\/lib64\/$libname\/$compiler@.
--
-- An additional complication is the need to support relocatable packages on
-- systems which support such things, like Windows.

-- Converting directories, absolute or prefix-relative

--
-- To prevent cyclic substitutions, only some variables are allowed in
-- particular dir templates. If out of scope vars are present, they are not
-- substituted for. Checking for any remaining unsubstituted vars can be done
-- as a subsequent operation.
--
-- The reason it is done this way is so that in 'prefixRelativeInstallDirs' we
-- can replace 'prefix' with the 'PrefixVar' and get resulting
-- 'PathTemplate's that still have the 'PrefixVar' in them. Doing this makes it
-- each to check which paths are relative to the $prefix.
