[options] All options but the ones listed below
are passed to diff.
[file1],[file2] Files to be compared
If no files are given, the program is
started anyway and you can select files
from within.
If only one file is given, the program
looks for an RCS/CVS directory next to the
file, and if found, runs in RCS/CVS mode.
Options:
-nodiff : Normally, if there are enough information on the
command line to run diff, Eskil will do so unless
this option is specified.
-dir : Start in directory diff mode. Ignores other args.
-clip : Start in clip diff mode. Ignores other args.
-noparse : Eskil can perform analysis of changed blocks to
-line : improve display. See online help for details.
-smallblock : The default. Do block analysis on small blocks.
-block : Full block analysis. This can be slow if there
are large change blocks.
-char : The analysis of changes can be done on either
-word : character or word basis. -char is the default.
-noignore : Don't ignore any whitespace.
-b : Ignore space changes. Default.
-w : Ignore all spaces.
-conflict : Treat file as a merge conflict file and enter merge
mode.
-o <file> : Specify merge result output file.
-browse : Automatically bring up file dialog after starting.
-server : Set up Eskil to be controllable from the outside.
-print <file> : Generate postscript and exit.
-limit <lines> : Do not process more than <lines> lines.}
