&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;At least the majority of the functionality implemented in the ETL is already implemented in the boost libraries, which have a very high quality, are broadly used, peer-reviewed and well tested. This effort is to replace the ETL with boost libraries, achieving simplified code with a more robust base.&lt;br /&gt;
&lt;br /&gt;
The replacement will be done in the following order:&lt;br /&gt;
# command-line interface (ONGOING)&lt;br /&gt;
# synfig modules&lt;br /&gt;
# synfig library&lt;br /&gt;
# synfig studio library&lt;br /&gt;
# synfig studio&lt;br /&gt;
Along the way I can most probably simplify/improve some stuff and make synfig's code cleaner.&lt;br /&gt;
&lt;br /&gt;
Follow the progress in [https://github.com/eldruin/synfig/tree/eldruin_etl_replacement this branch]&lt;br /&gt;

Here is a list of functions of the ETL and their replacement:&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|-&lt;br /&gt;
! ETL&lt;br /&gt;
! Boost equivalent&lt;br /&gt;
|-&lt;br /&gt;
| etl::filename_extension&lt;br /&gt;
| boost::filesystem::path::extension()&lt;br /&gt;
|-&lt;br /&gt;
| etl::filename_sans_extension&lt;br /&gt;
| boost::filesystem::path: combination of parent_path(), stem() and extension()&lt;br /&gt;
|-&lt;br /&gt;
| etl::basename&lt;br /&gt;
| boost::filesystem::path: combination of stem() and extension()&lt;br /&gt;
|-&lt;br /&gt;
| etl::dirname&lt;br /&gt;
| boost::filesystem::path::parent_path()&lt;br /&gt;
|-&lt;br /&gt;
| etl::clock&lt;br /&gt;
| boost::chrono::system_clock or high_resolution_clock&lt;br /&gt;
|-&lt;br /&gt;
| etl::strprintf&lt;br /&gt;
| boost::format()&lt;br /&gt;
