.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The import binder computes all the Fix function on records read from the given importer.
This importer doesn't change the current importer to the given one! Use the 'catmandu run'
command line command to control importers solely by the Fix script.

.SS "importer(\s-1IMPORTER_NAME,\s0 step: true|false, \s-1IMPORTER_ARGS...\s0)"
.IX Subsection "importer(IMPORTER_NAME, step: true|false, IMPORTER_ARGS...)"
Load the import \s-1IMPORTER_NAME\s0 in the current context. When step is 'true' then for
every execution of do \fBimporter()\fR only one item will be read from the importer. This
latter option can become handy in nested iterators:
