You can also make a t1x file that does *just* this job, if you don't
want to have to call that macro on every single rule.
<?xml version="1.0" encoding="utf-8"?>
<transfer>
<section-def-cats>
<def-cat n="any">
<cat-item tags="*"/>
</def-cat>
</section-def-cats>
<!-- … other required sections … -->
<section-rules>
<rule c="variant cleanup">
<pattern>
<pattern-item n="any"/>
</pattern>
<action>
<let><clip pos="1" side="tl" part="variety_tags"/><lit v=""/></let>
<out>
<lu>
<clip pos="1" side="sl" part="whole"/>
<lit v="/"/>
<clip pos="1" side="tl" part="whole"/>
</lu>
</out>
</action>
</rule>
</section-rules>
</transfer>
and in modes.xml, add
<program name="apertium-transfer -b" debug-suff="varclean"> <!-- add this -->
<file name="apertium-bar-foo.foo-bar.variety.t1x"/> <!-- your new file -->
<file name="foo-bar.variety.t1x.bin"/>
</program>
before your existing
<program name="apertium-transfer -b">
<file name="apertium-bar-foo.foo-bar.t1x"/>
<file name="foo-bar.t1x.bin"/>
</program>
