54/* MODULE NAME : RESTORE utility */
55/* */
56/* DESCRIPTIVE NAME : Restore one or more backed-up files from a */
57/* disk to another disk */
58/* */
59/* FUNCTION: Restore files saved by BACKUP utility to their */
60/* destination disk. This utility will be able to identify */
61/* which of the two backup formats was used and to do the */
62/* restore accordingly. */
63/* */
64/* NOTES: This RESTORE utility recognize two data formats: */
65/* 1. The data format used by BACKUP utility of 3.2 and before. */
66/* 2. The data format used by BACKUP utility of 3.3 and above, */
67/* and also used by CP/DOS 1.0 and above. */
68/* */
69/* DEPENDENCY: */
70/* This utility has a dependency on the BACKUP utility to */
71/* perform file backup correctly using the data structure */
72/* agreed on. */
73/* */
74/* RESTRICTION: */

85/* */
86/* Parameters: */
87/* The first parameter you specify is the drive designator of */
88/* the disk containing the backed up files. The second */
89/* parameter is the a filespec indicating which files you want */
90/* to restore. */
91/* Switches: */
92/* /S - Restore subdirectories too. */
93/* /P - If any hidden or read-only files match the filespec, */
94/* prompt the user for permission to restore them. */
95/* /B - Only restore those files which were last Revised on or */
96/* before the given date. */
97/* /A - Only restore those files which were last Revised on or */
98/* after the given date. */
99/* /E - Only restore those files which were last Revised at or */
100/* earlier then the given time. */
101/* /L - Only restore those files which were last Revised at or */
102/* later then the given time. */
103/* /M - Only restore those files which have been Revised since */

106/* destination disk. */
