The KOMA-Script Packages

KOMA-Script is more than just classes — the bundle also contains a number of packages. Some are generally useful, others are intended only for internal use by the KOMA-Script classes.

Generally useful packages

Package	Purpose
`typearea`	Compute margins and the type area on typographic grounds
`scrbase`	Foundational helpers — useful for users and other package authors
`scrextend`	Brings some KOMA-Script class features to other classes, especially the standard ones
`scrlayer`	Layer system for page styles plus page-style aliases
`scrlayer-scrpage`	Easy-to-configure page styles built on `scrlayer` — an alternative to `fancyhdr`, usable outside KOMA-Script too
`scrletter`	Core functionality of `scrlttr2` as a package, combinable with `scrartcl`, `scrreprt`, `scrbook` or the standard classes
`tocbasic`	Management of auxiliary file extensions (`.lof`, `.lot`, …), floats, caption configuration, and more
`scrdate`	ISO date formatting and locale-aware weekday names
`scrtime`	Formatting the current time
`scrfontsizes`	Generates font-size files for use with KOMA-Script classes or `scrextend`
`scrlogo`	Defines the command `\KOMAScript`

Deprecated or candidates for spinning off

The following packages are either deprecated or candidates for being moved out of KOMA-Script:

scraddr — access to .adr files.
scrdate, scrtime — may be split out as standalone projects.
scrlayer-notecolumn — proof of concept for layers with scrlayer.

Wrappers

scrjura — wrapper that keeps the old package name working after the package contract was moved out of the bundle.

Internal packages (not for users)

These packages are only used internally by KOMA-Script and should not be loaded directly by users or other package authors:

scrkbase — internal helpers.
scrlfile — file hooks; can be replaced by generic LaTeX hooks today.
scrlfile-hook — variant of scrlfile for current LaTeX kernels.
scrlfile-hook-3.34 — variant for older LaTeX kernels with a different hook syntax.
scrlfile-patcholdlatex — variant for LaTeX kernels without generic hooks.
