+ft2demos (freetype demos and tools)
+
+Set of demo programs and tools for freetype. Can be useful for testing
+and debugging problems with fonts (or with freetype itself). Includes
+these tools:
+
+ftbench  - benchmark some common FreeType paths
+ftchkwd  - test fixed font width
+ftdiff   - compare font hinting modes
+ftdump   - simple font dumper
+ftgamma  - screen gamma calibration helper
+ftgrid   - simple glyph grid viewer
+ftlint   - simple font tester
+ftmemchk - simple memory tester (tests FreeType's memory allocator)
+ftmulti  - multiple masters font viewer
+ftpatchk - tests whether patented hinting is necessary
+ftstring - string viewer (displays text in specified font)
+fttimer  - simple performance timer
+ftvalid  - font layout table validator
+ftview   - simple glyph viewer
+ttdebug  - a TrueType bytecode debugger
+
+Most of the commands have man pages. Also most of the commands show
+usage info if you run them with --help (or with no arguments).
+
+This package is known as "freetype2-demos" on Arch and Debian systems.

+# Slackware build script for ft2demos
+
+# Written by B. Watson (yalhcru@gmail.com)
+
+# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.
+
+# This thing requires first building (but not installing) freetype2,
+# hence all the downloads.
+
+# This script is heavily based on Pat Volkerding's freetype.SlackBuild:
+# https://slackware.uk/slackware/slackware-14.2/patches/source/freetype/
+# ...and Arch Linux's freetype2-demos PKGBUILD:
+# https://git.archlinux.org/svntogit/packages.git/tree/trunk?h=packages/freetype2
+
+# Note to self: keep VERSION in sync with Pat's patches/freetype.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
