+ <title>Installing a Shared Library</title>
+
+ <para>
+ If a shared library is created with the
+ &cv-link-SHLIBVERSION; variable set,
+ &scons; will create symbolic links as needed based on that
+ variable. To properly install such a library including the
+ symbolic links, use the &InstallVersionedLib; function.
+ </para>
+
+ <para>
+ For example, on a Linux system, this instruction:
+ </para>
+
+ <sconstruct>
+foo = env.SharedLibrary(target="foo", source="foo.c", SHLIBVERSION="1.2.3")
+ </sconstruct>
+
+ <para>
+ Will produce a shared library
+ <filename>libfoo.so.1.2.3</filename>
+ and symbolic links
+ <filename>libfoo.so</filename> and
+ <filename>libfoo.so.1</filename>
+ which point to
+ <filename>libfoo.so.1.2.3</filename>.
+ You can use the Node returned by the &SharedLibrary;
+ builder in order to install the library and its
+ symbolic links in one go without having to list
+ them individually:
+ </para>
+
+ <sconstruct>
+env.InstallVersionedLib(target="lib", source=foo)
+ </sconstruct>

+<!-- didn't get this to illustrate what I expected: example reports
