Usage

Options:

-h, --help output usage information
-V, --version output the version number
-c, --compare-content compare files by content
-D, --compare-date compare files by date
--date-tolerance [type] tolerance to be used in date comparison (milliseconds)
--compare-symlink compare files and directories by symlink
-f, --filter [type] file name filter
-x, --exclude [type] file/directory name exclude filter
-S, --skip-subdirs do not recurse into subdirectories
-L, --skip-symlinks ignore symlinks
-i, --ignore-case ignores case when comparing file names
-l, --show-left report - show entries occurring in left dir
-r, --show-right report - show entries occurring in right dir
-e, --show-equal report - show identic entries occurring in both dirs
-d, --show-distinct report - show distinct entries occurring in both dirs
-a, --show-all report - show all entries
-w, --whole-report report - include directories in detailed report
--reason report - show reason when entries are distinct
--csv report - print details as csv
--nocolors don't use console colors
--async Make use of multiple cores

By default files are compared by size.
--date-tolerance defaults to 1000 ms. Two files are considered to have
the same date if the difference between their modification dates fits
within date tolerance.

Exit codes:
0 - entries are identical
1 - entries are different
2 - error occurred

Examples:
compare by content dircompare -c dir1 dir2
show only different files dircompare -d dir1 dir2

The pattern is matched against the relative path of the entry being compared.

Following examples assume we are comparing two dir-compare code bases.
