+%D The system that is used to typeset this text is called \TEX,
+%D typeset with an lowered~E. From te beginning of \TEX,
+%D authors of macro packages adapted this raising and lowering
+%D style. In this module we define some of those logos.

+%D Alternative \CONTEXT\ logo, first Idris S.~Hamid's version:
+%D
+%D \def\Context
+%D {{\sc C\kern -.0667emo\kern -.0667emn\kern -.0549emt\kern
+%D -.1667em\lower.5ex\hbox {e}\kern -.125emx\kern -.0549emt}}

+ {E}\doifitalicelse\empty{\kern-.11em}X\kern-.055emT}}}
+
+%D The \METAFONT\ and \METAPOST\ logos adapt themselves to the
+%D current fontsize, an ugly but usefull hack.
