-/* OSM Binary file format 
-
-This is the master schema file of the OSM binary file format. This
-file is designed to support limited random-access and future
-extendability.
-
-A binary OSM file consists of a sequence of FileBlocks (please see
-fileformat.proto). The first fileblock contains a serialized instance
-of HeaderBlock, followed by a sequence of PrimitiveBlock blocks that
-contain the primitives.
-
-Each primitiveblock is designed to be independently parsable. It
-contains a string table storing all strings in that block (keys and
-values in tags, roles in relations, usernames, etc.) as well as
-metadata containing the precision of coordinates or timestamps in that
-block.
-
-A primitiveblock contains a sequence of primitive groups, each
-containing primitives of the same type (nodes, densenodes, ways,
-relations). Coordinates are stored in signed 64-bit integers. Lat&lon
-are measured in units <granularity> nanodegrees. The default of
-granularity of 100 nanodegrees corresponds to about 1cm on the ground,
-and a full lat or lon fits into 32 bits.
-
-Converting an integer to a lattitude or longitude uses the formula:
-$OUT = IN * granularity / 10**9$. Many encoding schemes use delta
-coding when representing nodes and relations.

-FAQ
----
-
-Q: What platforms does OSMR run on?
-A: Virtually any Unix-like platform with g++ installed. It has been developed
-   under Linux and tested on MacOS X 10.6. It should run under Windows as well
-   though the code will need some adjustments.
-   
-Q: What is the workflow to get the engine up and running
-A: Road network extraction->Preprocessing->Startup 
-
-Q: What does OSRM stand for?
-A: It is an abbreviation for Open Source Routing Machine.
-
-Q: What does HSGR stand for?
-A: It is an abbreviation for Hierarchy Search GRaph.
-
-Q: What is the .nodes file?
-A: It is a map that translates between internal and external Node IDs. Remember
-   that external NodeIDs can be arbitrary and non-contigous. Internally the
-   nodes are numbered from 0 to n-1.
-
-Q: The routing engine crashes with a seg-fault
-A: Check the startup parameters.
-
-Q: Something about the route is odd. I know that there is a better path
-A: Most probably it is missing data in the OSM file.
-
-Q: I work for this company that would like to use the code, but we are hesistant
-   because of the license.
-A: Contact me. Probably, we can work something out.
-
-Q: How fast is this thing?
-A: Good question. Here is a number. The engine was able to handle more than
-   2800 requests per Minute on the German road network with the travel time
-   metric on a Core 2 Duo. This also includes transfer of data across a 
-   switched 100MBit/s LAN. So, I guess it's fair to say it's fast.
-   
-Q: What is the difference between extractNetwork and extractLargeNetwork?
-A: extractNetwork does all of its magic in RAM, while extractLargeNetwork uses the
-   stxxl library to store the data in external memory. Use the first one for small
-   networks, but beware of running out of RAM. Swapping is the kiss of death. For
-   larger networks use extractLargeNetwork. It will be somewhat slower on the 
-   smaller files, but way faster with large ones like the planet file.

Docs/KnownBugs.txt

@@ -1,6 +0,0 @@
-- extractorLargeNetwork finishes with: 
-  terminate called after throwing an instance of 'stxxl::resource_error'
-  what():  Error in function void stxxl::mutex::lock() pthread_mutex_lock(&_mutex) Invalid argument
-
-  This ist a known, albeit odd behavior that is caused by a bug in stxxl. It can be ignored. Upgrade
-  to version 1.3.1 of stxxl.
