<para>
<link linkend="GCutProcess"><type>GCutProcess</type></link> encapsulates external command execution,
communication and termination. <link linkend="GCutProcess"><type>GCutProcess</type></link> reports an error
as <link linkend="GError"><type>GError</type></link>. It can be asserted easily by
<link linkend="gcut-assert-error"><function>gcut_assert_error()</function></link>.
</para>
<para>
External command is specified to constructor like
<link linkend="gcut-process-new"><function>gcut_process_new()</function></link>, <link linkend="gcut-process-new-strings"><function>gcut_process_new_strings()</function></link> and so
on. External command isn't run at the
time. <link linkend="gcut-process-run"><function>gcut_process_run()</function></link> runs specified external command.
</para>
<para>
Standard/Error outputs of external command are passed by
<link linkend="GCutProcess-output-received"><type>"output-received"</type></link>/<link linkend="GCutProcess-error-received"><type>"error-received"</type></link> signals
or <link linkend="GIOChannel"><type>GIOChannel</type></link> returned by
<link linkend="gcut-process-get-output"><function>gcut_process_get_output()</function></link>/<link linkend="gcut-process-get-error"><function>gcut_process_get_error()</function></link>.
<link linkend="gcut-process-write"><function>gcut_process_write()</function></link> writes a chunk to standard input of
external command.
</para>
<para>
To wait external command finished, <link linkend="gcut-process-wait"><function>gcut_process_wait()</function></link> can be
used. It accepts timeout to avoid infinite waiting.
