Summary description: Inlined expansions within definitions
License type: lppl

Announcement text: 
----------------------------------------------------------------------
This package provides a macro \Inline that precedes a \def or \gdef.  
Within the definition text of an inlined definition, keywords such as 
\Expand may be used to selectively inline certain expansions at 
definition-time.  This eases the process of redefining macros in terms 
of the original definition, as well as definitions in which the token 
that must be expanded is deep within, where \expandafter would be 
difficult and \edef is not suitable.  Another application is as an 
easier version of \aftergroup, by defining a macro in terms of 
expanded local variables, then ending the group with 
\expandafter\endgroup\macro
