@cindex CTAN
Import metadata from @uref{http://www.ctan.org/, CTAN}, the
comprehensive TeX archive network for TeX packages that are part of the
@uref{https://www.tug.org/texlive/, TeX Live distribution}.
Information about the package is obtained through the XML API provided
by CTAN, while the source code is downloaded from the SVN repository of
the Tex Live project. This is done because the CTAN does not keep
versioned archives.
The command command below imports metadata for the @code{fontspec}
TeX package:
@example
guix import texlive fontspec
@end example
When @code{--archive=DIRECTORY} is added, the source code is downloaded
not from the @file{latex} sub-directory of the @file{texmf-dist/source}
tree in the TeX Live SVN repository, but from the specified sibling
directory under the same root.
The command below imports metadata for the @code{ifxetex} package from
CTAN while fetching the sources from the directory
@file{texmf/source/generic}:
@example
guix import texlive --archive=generic ifxetex
@end example

;;; Commentary:
;;;
;;; Generate a package declaration template for the latest version of a
;;; package on CTAN, using the XML output produced by the XML API to the CTAN
;;; database at http://www.ctan.org/xml/1.2/
;;;
;;; Instead of taking the packages from CTAN, however, we fetch the sources
;;; from the SVN repository of the Texlive project. We do this because CTAN
;;; only keeps a single version of each package whereas we can access any
;;; version via SVN. Unfortunately, this means that the importer is really
;;; just a Texlive importer, not a generic CTAN importer.
