+.SH DESCRIPTION
+
+IcePatch2 tool to compress files and calculate checksums. Full documentation
+for icepatch2calc is available online at:

+

+.br
+Normally, icepatch2calc scans the data directory and compresses a file only
+if no compressed version exists, or if the compressed version of a file has a
+modification time that predates that of the uncompressed version. If you
+specify -z, the tool re-scans and recompresses the entire data directory,
+regardless of the time stamps on files. This option is useful if you suspect
+that time stamps in the data directory may be incorrect.
+
+.TP
+.BR \-Z ", " \-\-no-compress\fR
+.br
+This option allows you to create a client-side checksum file. Do not use this
+option when creating the checksum file for the server — the option is for 
+creating a client-side IcePatch2.sum file for updates of software on
+distribution media.
+
+.TP
+.BR \-i ", " \-\-case\-insensitive\fR
+.br
+This option disallows file names that differ only in case. (An error message
+will be printed if icepatch2calc encounters any files that differ in case
+only.) This is particularly useful for Unix servers with Windows clients, 
+since Windows folds the case of file names, and therefore such files would
+override each other on the Windows client.
+
+.TP
+.BR \-V ", " \-\-verbose\fR
+.br
+This option prints a progress message for each file that is compressed and for
+each checksum that is computed.
