+     "@acronym{PSF, PC Screen Font} is the simple monospaced bitmap font format
+used by the Linux kernel for console fonts.  The PSF Tools convert between PSF
+and many other font formats, similar to what the NetPBM package does for images.
+
+It includes converters for a good number of common bitmap font formats such as
+@file{.BDF}, @file{.FNT}, and @file{.FON} files, Berkeley vfonts, classic
+Amstrad/Sinclair/Hercules/BBC Micro soft fonts, and raw (DOS-style) fonts.
+
+It also supports less traditional formats such as PBM/XBM images, plain text
+(for rudimentary editing), and C header files.")
