+=head1 NAME
+
+B<liteimg> - Modify statelite image by creating a series of links.
+
+=head1 SYNOPSIS
+
+I<liteimg [-h| --help]>
+
+I<liteimg  [-v| --version]>
+
+I<liteimg [-o OS] [ -p profile] [-a architecture]>
+
+I<liteimg imagename>
+
+=head1 DESCRIPTION
+
+This command modifies the statelite image by creating a series of links. 
+It creates 2 levels of indirection so that files can be modified while in
+their image state as well as during runtime. For example, a file like
+<$imgroot>/etc/ntp.conf will have the following operations done to it:
+
+I<    mkdir -p $imgroot/.default/etc>
+
+I<    mkdir -p $imgroot/.statelite/tmpfs/etc>
+
+I<    mv $imgroot/etc/ntp.conf $imgroot/.default/etc>
+
+I<    cd $imgroot/.statelite/tmpfs/etc>
+
+I<    ln -sf ../../../.default/etc/ntp.conf .>
+
+I<    cd $imgroot/etc>
+
+I<    ln -sf ../.statelite/tmpfs/etc/ntp.conf .>
+
+
+When finished, the original file will reside in
+I<$imgroot/.default/etc/ntp.conf>. I<$imgroot/etc/ntp.conf> will link to
+I<$imgroot/.statelite/tmpfs/etc/ntp.conf> which will in turn link to
+I<$imgroot/.default/etc/ntp.conf>
+
+Note: If you make any changes to your litefile table after running liteimg then you will need to rerun liteimg again.
+
