+This file contains a list of various font formats. It gives the
+reference document and whether it is supported in FreeType 2.
+
+
+ file type:
+ The only special case is `MAC'; on older Mac OS versions, a `file'
+ is stored as a data and a resource fork, this is, within two
+ separate data chunks. In all other cases, the font data is stored
+ in a single file.
+
+ wrapper format:
+ The format used to represent the font data. In the table below it
+ is used only if the font format differs. Possible values are
+ `SFNT' (binary), `PS' (a text header, followed by binary or text
+ data), and `LZW' (compressed with either `gzip' or `compress').
+
+ font format:
+ How the font is to be accessed, possibly after converting the file
+ type and wrapper format into a generic form. Bitmap formats are
+ `BDF', `PCF', and one form of `WINFNT'; all others are vector
+ formats.
+
+ font type:
+ Sub-formats of the font format. `SBIT' and `MACSBIT' are bitmap
+ formats, `MM' and `VAR' support optical axes.
+
+ glyph access:
+ If not specified, the glyph access is `standard' to the font
+ format. Values are `CID' for CID-keyed fonts, `SYNTHETIC' for
+ fonts which are modified versions of other fonts by means of a
+ transformation matrix, `COLLECTION' for collecting multiple fonts
+ (sharing most of the data) into a single file, and `TYPE_0' for PS
+ fonts which are to be accessed in a tree-like structure.
+
+ FreeType driver:
+ The module in the FreeType library which handles the specific font
+ format. A missing entry means that FreeType doesn't support the
+ font format (yet).
+
+
+Please send additions and/or corrections to [email protected] or to the
+FreeType developer's list at devel@freetype (for subscribers only). If
+you can provide a font example for a format which isn't supported yet
+please send a mail too.
