<H1><A NAME="description">DESCRIPTION</A></H1>
<P>Locates the full path to the script bin directory to allow the use
of paths relative to the bin directory.</P>
<P>This allows a user to setup a directory tree for some software with
directories <root>/bin and <root>/lib and then the above example will allow
the use of modules in the lib directory without knowing where the software
tree is installed.</P>
<P>If perl is invoked using the <STRONG>-e</STRONG> option or the perl script is read from
<CODE>STDIN</CODE> then FindBin sets both <CODE>$Bin</CODE> and <CODE>$RealBin</CODE> to the current
directory.</P>
<P>
<HR>
<H1><A NAME="exportable variables">EXPORTABLE VARIABLES</A></H1>
<PRE>
$Bin - path to bin directory from where script was invoked
$Script - basename of script from which perl was invoked
$RealBin - $Bin with all links resolved
$RealScript - $Script with all links resolved</PRE>

<P>if perl is invoked as</P>
<PRE>
perl filename</PRE>
<P>and <EM>filename</EM> does not have executable rights and a program called <EM>filename</EM>
exists in the users <CODE>$ENV{PATH}</CODE> which satisfies both <STRONG>-x</STRONG> and <STRONG>-T</STRONG> then FindBin
assumes that it was invoked via the <CODE>$ENV{PATH}</CODE>.</P>
<P>Workaround is to invoke perl as</P>

perl ./filename</PRE>
