arch linux's only supported binary platform is x86_64. the arch package repositories and user repository (aur) contain 58,000 binary and source packages, which comes close to debian linux's 68,000 packages; however, the two distributions' approaches to packaging differ, making direct comparisons difficult. for example, six out of arch's 58,000 packages comprise the software abiword, of which three in the user repository replace the canonical abiword package with an alternative build type or version (such as sourcing from the latest commit to abiword's source control repository), whereas debian installs a single version of abiword across seven packages. the arch user repository also contains a writerperfect package which installs several document format converters, while debian provides each of the more than 20 converters in its own subpackage.
