+=head1 NAME
+
+ExtUtils::HasCompiler - Check for the presence of a compiler
+
+=head1 VERSION
+
+version 0.021
+
+=head1 SYNOPSIS
+
+ use ExtUtils::HasCompiler 'can_compile_extension';
+ if (can_compile_extension()) {
+ ...
+ }
+ else {
+ ...
+ }
+
+=head1 DESCRIPTION
+
+This module tries to check if the current system is capable of compiling, linking and loading an XS module.
+
+B<Notice>: this is an early release, interface stability isn't guaranteed yet.
+
+=head1 FUNCTIONS
+
+=head2 can_compile_loadable_object(%opts)
+
+This checks if the system can compile, link and load a perl loadable object. It may take the following options:
+
+=over 4
+
+=item * quiet
+
+Do not output the executed compilation commands.
+
+=item * config
+
+An L<ExtUtils::Config|ExtUtils::Config> (compatible) object for configuration.
+
+=item * skip_load
+
+This causes can_compile_loadable_object to not try to load the generated object. This defaults to true on a cross-compiling perl.
+
+=back
+
+=head2 can_compile_static_library(%opts)
+
+This checks if the system can compile and link a perl static library. It does not check it it can compile a new perl with it. It may take the following options:
+
+=over 4
+
+=item * quiet
+
+Do not output the executed compilation commands.
+
+=item * config
+
+An L<ExtUtils::Config|ExtUtils::Config> (compatible) object for configuration.
+
+=back
+
+=head2 can_compile_extension(%opts)
+
+This will call either C<can_compile_loadable_object>, or C<can_compile_static_library>, depending on which is the default on your configuration. In addition to the arguments listed above, it can take one more optional argument:
+
+=over 4
+
+=item * linktype
+
+This will force the linktype to be either static or dynamic. Dynamic compilation on a static perl won't work, but static libraries can be viable on a dynamic perl.
