<title>Default Phase Functions</title>
<para>
Each of the default src_* phase functions is now accessible
via a function having a name that begins with default_ and
ends with the respective phase function name. For example,
a call to a function with the name default_src_compile is
equivalent to a call to the default src_compile
implementation.
</para>

<sect3 id='package-ebuild-eapi-2-phases-default-function-alias'>
<title>Default Phase Function Alias</title>
<para>
A function named "default" is redefined for each phase so that it
will call the default_* function corresponding to the current phase.
For example, a call to the function named "default" during the
src_compile phase is equivalent to a call to the function named
default_src_compile.
