+par2cmdline (Commandline implementation of PARv2.0 specification)
+
+par2cmdline is a GPL-licensed commandline tool for creating and using PAR2 
+parity sets to detect damage in files and repair them if necessary. The 
+program uses Reed Solomon Coding to perform its error correction. A useful 
+program for checking and ensuring the integrity of binaries retrieved from 
+usenet for instance.
+
+Several patches have been included to fix compilation issues on current
+platforms.

+.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.
+
+.SH REED SOLOMON CODING
+
+PAR2 uses Reed Solomon Coding to perform its calculations. For details of this
+coding technique try the following link:

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
