XThe following copy of INDENT includes modifications made by Mark London,
XMRL@NERUS.PFC.MIT.EDU. It was tested with many different C sources as input
Xfiles.  Many of the changes were made necessary due to the original program
V not
Xbeing able to very easily handle structure initializations, particularly tho
Vse
Xfound in DECWINDOWS/X programs. `20
X
XINDENT has been modified by different people, so different versions exist.
XThe HELP file contained here does not include all the possible qualifiers of
Xthis version, as it was obtained on a machine with a different version.  Mos
Vt
Xof the important qualifiers are mentioned, however, including some that I ha
Vve
Xadded.  To see undocumented commands, look at ARGS.C.  Note that I have
Xeliminated the code which creates a backup copy of the source, as that is
Xunnecessary under VMS.  I also have modified it so if only the file prefix
Xis specified on the command line, it assumes the suffix is .C .
