 Macro Details
 =============
 
   Due to unavoidable disparities in the TeX and `makeinfo'
 implementations, Texinfo macros have the following limitations.
 
    * All macros are expanded inside at least one TeX group.  This means
      that
 
    * Macros containing a command which must be on a line by itself,
      such as a conditional, cannot be invoked in the middle of a line.
 
    * The TeX implementation cannot construct macros that define macros
      in the natural way.  To do this, you must use conditionals and raw
      TeX.  For example:
 
           @ifinfo
           @macro ctor {name, arg}
           @macro \name\
           something involving \arg\ somehow
           @end macro
           @end macro
           @end ifinfo
           @tex
           \gdef\ctor#1{\ctorx#1,}
           \gdef\ctorx#1,#2,{\def#1{something involving #2 somehow}}
           @end tex
 
    * It is best to avoid comments inside macro definitions.
