=item xsinit()
This will generate code with an B<xs_init> function that glues the perl B<Socket::bootstrap> function
-to the C B<boot_Socket> function and writes it to a file named "xsinit.c".
+to the C B<boot_Socket> function and writes it to a file named F<xsinit.c>.
Note that B<DynaLoader> is a special case where it must call B<boot_DynaLoader> directly.
When looking for B<DBD::Oracle> relative to a search path,
we should find B<auto/DBD/Oracle/Oracle.a>
-Keep in mind, you can always supply B</my/own/path/ModuleName.a>
+Keep in mind that you can always supply B</my/own/path/ModuleName.a>
as an additional linker argument.

+Where:
B<$std> is boolean, equivalent to the B<-std> option.
perl -MExtUtils::Embed -e ldopts
-This will print arguments for linking with B<libperl.a>, B<DynaLoader> and
+This will print arguments for linking with B<libperl> and
extensions found in B<$Config{static_ext}>. This includes libraries
found in B<$Config{libs}> and the first ModuleName.a library
for each extension that is found by searching B<@INC> or the path
This will do the same as the above example, along with printing additional arguments for linking with the B<Socket> extension.
-
- perl -MExtUtils::Embed -e ldopts -- DynaLoader
-
-
-This will print arguments for linking with just the B<DynaLoader> extension
-and B<libperl.a>.
-
-
perl -MExtUtils::Embed -e ldopts -- -std Msql -- -L/usr/msql/lib -lmsql
-
Any arguments after the second '--' token are additional linker
arguments that will be examined for potential conflict. If there is no
conflict, the additional arguments will be part of the output.
This function returns a string of calls to B<newXS()> that glue the module B<bootstrap>
function to B<boot_ModuleName> for each @modules.
-B<xsinit()> uses the xsi_* functions to generate most of it's code.
