.SH NAME
Dpkg::Arch \- handle architectures
.SH DESCRIPTION
.IX Header "DESCRIPTION"
The Dpkg::Arch module provides functions to handle Debian architectures,
wildcards, and mapping from and to GNU triplets.
.PP
No symbols are exported by default. The :all tag can be used to import all
symbols. The :getters, :parsers, :mappers and :operators tags can be used
to import specific symbol subsets.
