Finding the data stuff isn't difficult, use a replacement:
<file name="named_colors.txt" role="data"/> <file name="filethatusesit.php" role="php> <replace from="@data-dir@" to="data_dir" type="pear-config"/> </file>
and in filethatusesit.php:
<?php // ... $namedcolorslocation = '@data-dir@/named_colors.txt'; $fp = fopen($namedcolorslocation);
Note that this does not work if using Horde's create_symlinks.php to install PEAR packages.
