-.SH EXAMPLES
-
-With PAR 2.0 you can create PAR2 recovery files for as few as 1 or as many as
-32768 files. If you wanted to create PAR1 recovery files for a single file
-you are forced to split the file into muliple parts and RAR is frequently
-used for this purpose. You do NOT need to split files with PAR 2.0.
-
-To create PAR 2 recovery files for a single data file (e.g. one called
-test.mpg), you can use the following command:
-
-  par2 create test.mpg
-
-If test.mpg is an 800 MB file, then this will create a total of 8 PAR2 files
-with the following filenames (taking roughly 6 minutes on a PC with a
-1500MHz CPU):
-
-  test.mpg.par2 	 - This is an index file for verification only
-  test.mpg.vol00+01.par2 - Recovery file with 1 recovery block
-  test.mpg.vol01+02.par2 - Recovery file with 2 recovery blocks
-  test.mpg.vol03+04.par2 - Recovery file with 4 recovery blocks
-  test.mpg.vol07+08.par2 - Recovery file with 8 recovery blocks
-  test.mpg.vol15+16.par2 - Recovery file with 16 recovery blocks
-  test.mpg.vol31+32.par2 - Recovery file with 32 recovery blocks
-  test.mpg.vol63+37.par2 - Recovery file with 37 recovery blocks
-
-The test.mpg.par2 file is 39 KB in size and the other files vary in size from
-443 KB to 15 MB.
-
-These par2 files will enable the recovery of up to 100 errors totalling 40 MB
-of lost or damaged data from the original test.mpg file when it and the par2
-files are posted on UseNet.
-
-When posting on UseNet it is recommended that you use the "-s" option to set
-a blocksize that is equal to the Article size that you will use to post the
-data file. If you wanted to post the test.mpg file using an article size
-of 300 KB then the command you would type is:
-
-  par2 create -s307200 test.mpg
-
-This will create 9 PAR2 files instead of 8, and they will be capable of
-correcting up to 134 errors totalling 40 MB. It will take roughly 8 minutes
-to create the recovery files this time.
-
-In both of these two examples, the total quantity of recovery data created
-was 40 MB (which is 5% of 800 MB). If you wish to create a greater or lesser
-quantity of recovery data, you can use the "-r" option.
-
-To create 10% recovery data instead of the default of 5% and also to use a
-block size of 300 KB, you would use the following command:
-
-  par2 create -s307200 -r10 test.mpg
-
-This would also create 9 PAR2 files, but they would be able to correct up to
-269 errors totalling 80 MB. Since twice as much recovery data is created, it
-will take about 16 minutes to do so with a 1500MHz CPU.
-
-The "-u" and "-n" options can be used to control exactly how many recovery
-files are created and how the recovery blocks are distributed amoungst them.
-They do not affect the total quantity of recovery data created.
-
-The "-f" option is used when you create additional recovery data.
-
-e.g. If you have already created 10% and want another 5% then you migh use
-the following command:
-
-  par2 create -s307200 -r5 -f300 test.mpg
-
-This specifies the same block size (which is a requirement for additional
-recovery files), 5% recovery data, and a first block number of 300.
-
-The "-m" option controls how much memory par2 uses. It defaults to
-16 MB unless you override it.
-
-CREATING PAR2 FILES FOR MULTIPLE DATA FILES
-
-When creating PAR2 recovery files form multiple data files, you must specify
-the base filename to use for the par2 files and the names of all of the data
-files.
-
-If test.mpg had been split into multiple RAR files, then you could use:
-
-  par2 create test.mpg.rar.par2 test.mpg.part*.rar
-
-The files filename "test.mpg.rar.par2" says what you want the par2 files to
-be called and "test.mpg.part*.rar" should select all of the RAR files.
-
-VERIFYING AND REPAIRING
-
-When using par2 recovery files to verify or repair the data files from
-which they were created, you only need to specify the filename of one
-of the par2 files to par2.
-
-e.g.:
-
-  par2 verify test.mpg.par2
-
-This tells par2 to use the information in test.mpg.par2 to verify the
-data files.
-
-par2 will automatically search for the other par2 files that were
-created and use the information they contain to determine the filenames
-of the original data files and then to verify them.
-
-If all of the data files are ok, then par2 will report that repair
-will not be required.
-
-If any of the data files are missing or damaged, par2 will report
-the details of what it has found. If the recovery files contain enough
-recovery blocks to repair the damage, you will be told that repair is
-possible. Otherwise you will be told exactly how many recovery blocks
-will be required in order to repair.
-
-To carry out a repair use the following command:
-
-  par2 repair test.mpg.par2
-
-This tells par2 to verify and if possible repair any damaged or
-missing files. If a repair is carried out, then each file which is
-repaired will be re-verified to confirm that the repair was successful.
-
-MISSNAMED AND INCOMPLETE DATA FILES
-
-If any of the recovery files or data files have the wrong filename, then
-par2 will not automatically find and scan them.
-
-To have par2 scan such files, you must include them on the command
-line when attempting to verify or repair.
-
-e.g.:
-
-  par2 r test.mpg.par2 other.mpg
-
-This tells par2 to scan the file called other.mpg to see if it
-contains any data belonging to the original data files.
-
-If one of the extra files specified in this way is an exact match
-for a data file, then the repair process will rename the file so that
-it has the correct filename.
-
-Because par2 is designed to be able to find good data within a
-damaged file, it can do the same with incomplete files downloaded from
-UseNet. If some of the articles for a file are missing, you should still
-download the file and save it to disk for par2 to scan. If you
-do this then you may find that you can carry out a repair in a situation
-where you would not otherwise have sufficient recovery data.
-
-You can have par2 scan all files that are in the current directory
-using a command such as:
-
-  par2 r test.mpg.par2 *
-
-WHAT TO DO WHEN YOU ARE TOLD YOU NEED MORE RECOVERY BLOCKS
-
-If par2 determines that any of the data files are damaged or
-missing and finds that there is insufficient recovery data to effect
-a repair, you will be told that you need a certain number of recovery
-blocks. You can obtain these by downloading additional recovery files.
-
-In order to make things easy, par2 files have filenames that tell you
-exactly how many recovery blocks each one contains.
-
-Assuming that the following command was used to create recovery data:
-
-  par2 c -b1000 -r5 test.mpg
-
-Then the recovery files that are created would be called:
-
-  test.mpg.par2
-  test.mpg.vol00+01.par2
-  test.mpg.vol01+02.par2
-  test.mpg.vol03+04.par2
-  test.mpg.vol07+08.par2
-  test.mpg.vol15+16.par2
-  test.mpg.vol31+19.par2
-
-The first file in this list does not contain any recovery data, it only
-contains information sufficient to verify the data files.
-
-Each of the other files contains a different number of recovery blocks.
-The number after the '+' sign is the number of recovery blocks and the
-number preceding the '+' sign is the block number of the first recovery
-block in that file.
-
-If par2 told you that you needed 10 recovery blocks, then you would
-need "test.mpg.vol01+02.par2" and "test.mpg.vol07+08.par". You might of course
-choose to fetch "test.mpg.vol15+16.par2" instead (in which case you would have
-an extra 6 recovery blocks which would not be used for the repair).
-
-.SH NOTES
-
-This version of par2 does not support recording path information for
-files. Whilst you can create recovery files for files from multiple locations,
-it will expect all files to be in the current directory when verifying and
-repairing. This limitation will be corrected in an update.
