troffcvt supports the following groff extensions to standard troff:

*
  Long names. Contexts in which long names are legal include:

     .xxx         Long request and macro names
     \[xxx]       Long special character names
     \*[xxx]      Long string names
     \n[xxx]      Long register names
     \f[xxx]      Long font names
     \$[nnn]      Long (>9) macro argument references

  -C option.

  The \$* and \$@ macro argument references.
