/** Provides an interfase to convert from tibetan text transliterated in the Acip scheme to THDL's <a href="http://orion.lib.virginia.edu/thdl/tools/ewts.pdf" target="_blank">Extended Wylie</a> scheme.

<p>If no arguments are sent, it takes the Acip text from the standard input and sends the 
Wylie text to the standard output. If one argument is sent, it interprets it as the
file name for the input. If two arguments are sent, it interprets the first one as the file name for the input and
the second one as the file name for the output. For example, the following 
command converts the <i>lam-rim-chen-mo.act</i> storing the results in <i>
lam-rim-chen-mo.txt</i>:</p>
<pre>java -cp DictionarySearchStandalone.jar org.thdl.tib.scanner.AcipToWylie lam-rim-chen-mo.act lam-rim-chen-mo.txt</pre>
<p>Alternatively by redirecting the standard input/output you perform the same 
job:</p>
<pre>java -cp DictionarySearchStandalone.jar org.thdl.tib.scanner.AcipToWylie &lt; lam-rim-chen-mo.act &gt; lam-rim-chen-mo.txt</pre>
<p>If you only want to display the results to the screen, you can run:</p>
<pre>java -cp DictionarySearchStandalone.jar org.thdl.tib.scanner.AcipToWylie lam-rim-chen-mo.act | more</pre>
