/* Tool to migrate existing user settings from GConf to GSettings
*
* This tool will first run some sanity checks to see if migration
* is necessary/possible. The actual migration works directly from
* the GConf .xml files. Using an xsl transform it will convert them
* in a guile script to set most settings found.
*
* Notes:
* - due to some limitations in the xslt code, all the gconf xml files are
* first copied into a temporary directory. After the migration has finished,
* that temporary directory and its contents are removed.
* - not all settings can be migrated. All the important ones are though.
* The ones that are missing are mostly with respect to window position
* and size.
* - column widths/visibilities, sorting orders,... are no longer stored
* in gsettings, so these will obviously not be migrated either.
* - upon a successful run, a flag will be set to prevent the migration
* from running again. So in normal circumstances the migration will
* be executed only once.
