       This Doulos SIL font is essentially the same design as the SIL Doulos font first released by SIL in 1992. The design has been changed from the original in that it has been scaled down to be a better match with contemporary digital fonts, such as Times New Roman®. This current release is a regular typeface, with no bold or italic version available or planned. It is intended for use alongside other Times-like fonts where a range of styles (italic, bold) are not needed. Therefore, just one font is included in the Doulos SIL release: Doulos SIL Regular.

It has been designed for use in a wide variety of applications; it has no direct dependencies on Ogg encapsulation, though it is most commonly used in conjunction with liboggz to decode or encode FLAC, Speex or Vorbis audio tracks in Ogg files, including Ogg Theora and Annodex.

       Welcome to Liberal Crime Squad! The Conservatives have taken the Executive, Legislative, and Judicial branches of government. Over time, the Liberal laws of this nation will erode and turn the country into a BACKWOODS YET CORPORATE NIGHTMARE. To prevent this from happening, the Liberal Crime Squad was established. The mood of the country is shifting, and we need to turn things around. Go out on the streets and indoctrinate Conservative automatons. That is, let them see their True Liberal Nature.

It typically has no dependencies other than the Linux kernel, C standard library, and libdl (for dynamic linking). While ELL is designed to be efficient and compact enough for use on embedded Linux platforms, it is not limited to resource-constrained systems.
