(absolute or relative) of the directory where the library will reside.
It must designate an existing directory, and this directory must be
different from the project's object directory. It also needs to be writable.
+The directory should only be used for one library; the reason is that all

If both @code{Library_Name} and @code{Library_Dir} are specified and
are legal, then the project file defines a library project. The optional
The @code{Library_Kind} attribute has a string value that must be one of the
following (case insensitive): @code{"static"}, @code{"dynamic"} or
-@code{"relocatable"}. If this attribute is not specified, the library is a
-static library, that is an archive of object files that can be potentially
-linked into an static executable. Otherwise, the library may be dynamic or
+@code{"relocatable"} (which is a synonym for @code{"dynamic"}). If this
+attribute is not specified, the library is a static library, that is
+an archive of object files that can be potentially linked into an
+static executable. Otherwise, the library may be dynamic or
relocatable, that is a library that is loaded only at the start of execution.
-Depending on the operating system, there may or may not be a distinction
-between dynamic and relocatable libraries. For Unix and VMS Unix there is no
-such distinction.
If you need to build both a static and a dynamic library, you should use two
different object directories, since in some cases some extra code needs to
