TITLE:		Source Code Indexing
LFS VERSION:	ALL
AUTHOR:		Tom Judge <tomjude@orange.net>

SYNOPSIS:
    A small PHP script to catalog all of the source code required to build a LFS
    system to make it easyer to find the source that you are looking for.

HINT:
    Ver: 1.0
    28/12/2001
    
    This script requires PHP v4.
    
    The script will extract all of bz2 files and then move them to a directory
    with the same name as the first character of the file name.  Then if the 
    file is a tarball it extracts the contents and removes the original file.
    
    The code is listeb below, some lines have been been truncated, these lines
    end in '\' and will have to un-truncated in order for the script to work
    completely.

    #!/usr/bin/php

    <?
    exec ("nice -20 bunzip2 *.bz2");
    $dirs = array (a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, \
	u, v, w, x, y, z);
    $i = 0;
    $num = count($dirs);
    while ( $i < $num ) {
    	exec("mkdir $dirs[$i]");
	$i++;
    }

    $handle = opendir('.');
    $i = 0;

    while (($file = readdir($handle))!==false) {
	if ( !is_dir($file) ) {
	    $array[$i] = $file;
	    $i++;
	}
    }
    closedir($handle);

    $num = count($array);
    $i = 0;

    while ( $i < $num ) {
	if ( $array[$i] != "relocate" ) {
	    $tmp = $array[$i];
	    $letter = substr( $tmp, 0, 1);
	    $dir = $letter . "/";
	    echo "Moving $tmp to $letter .....";
	    exec ("mv $tmp $dir");
	    echo "Done.\n";
	    $ext = substr( $tmp, -3, 3);
	    if ( $ext == "tar" ) {
		echo "Changing Dir to $dir .....";
		chdir($letter);
		echo "Done.\n";
		echo "Un-taring Archive $tmp .....";
		exec("tar -xf $tmp");
		echo "Done.\n";
		echo "Removing Archive $tmp .....";
		exec("rm -f $tmp");
		echo "Done.\n";
		echo "Changin Back to src dir .....";
		chdir("..");
		echo "Done.\n";
	    }
	}
	$i++;
    }
    ?>

    The Future:
	In future is plan to make a bash script version of this script and a c++
	version so that users without PHP can utilise it.
