>This manages everything to do with where files get installed (though does
 not get involved with actually doing any installation). It provides an
 <TT
><A HREF="Distribution-Simple-InstallDirs.html#t%3AInstallDirs"
>InstallDirs</A
></TT
> 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 <TT
>$prefix</TT
> and by
 changing the prefix all other dirs still end up changed appropriately. So it
 provides a <TT
><A HREF="Distribution-Simple-InstallDirs.html#t%3APathTemplate"
>PathTemplate</A
></TT
> type and functions for substituting for these
 templates.

</P

>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 $-style variables in the dirs.
 These are expanded by textual substituion (see <TT
><A HREF="Distribution-Simple-InstallDirs.html#v%3AsubstPathTemplate"
>substPathTemplate</A
></TT
>).
</P
><P
>A few of these installation directories are split into two components, the
 dir and subdir. The full installation path is formed by combining the two
 together with <TT
>/</TT
>. The reason for this is compatibility with other unix
 build systems which also support <TT
>--libdir</TT
> and <TT
>--datadir</TT
>. We would like
 users to be able to configure <TT
>--libdir=/usr/lib64</TT
> for example but
 because by default we want to support installing multiple versions of
 packages and building the same package for multiple compilers we append the
 libsubdir to get: <TT
>/usr/lib64/$pkgid/$compiler</TT
>.
</P
><P
>An additional complication is the need to support relocatable packages on
 systems which support such things, like Windows.
