-# Dr. Memory
-
-Dr. Memory (www.drmemory.org) is an open-source dynamic memory
-monitoring tool for Windows, Linux, and Mac.
-
-## About Dr. Memory
-
-Dr. Memory operates on unmodified application binaries running on
-Windows, Linux, or Mac on commodity x86 and ARM32 (forthcoming) hardware.
-It is capable of identifying memory-related programming errors including:
-  * accesses of uninitialized memory
-  * accesses to unaddressable memory (heap underflow and overflow)
-  * accesses to freed memory
-  * double frees
-  * memory leaks
-  * handle leaks (on Windows)
-  * GDI API usage errors (on Windows)
-  * accesses to un-reserved thread local storage slots (on Windows)
-
-## Using Dr. Memory (Windows only)
-
-Build your application with debug information and then run it under
-Dr. Memory.  Errors found are printed to the screen, and a summary is
-shown at the end of the run.
-
-### Obtain Dr. Memory
-
-The Dr. Memory package is provided as a self-extracting archive
-(DrMemory-Windows-sfx.exe) in tools/drmemory directory, which can be
-extracted by running command 'DrMemory-Windows-sfx.exe -ounpacked -y'.
-
-The Dr. Memory release package can be downloaded from
-https://github.com/DynamoRIO/drmemory/wiki/Downloads.
-
-Nightly builds can be downloaded from
-https://build.chromium.org/p/client.drmemory/builds/.
-
-The Dr. Memory source code can be found at
-https://github.com/DynamoRIO/drmemory.
-
-### Run your application with Dr. Memory
-
-To run your application with Dr. Memory, simply put 'drmemory.exe --'
-before the command that invokes the application.
-
-  * Running pdfium_unittests with Dr. Memory:
-    tools\drmemory\unpaced\bin\drmemory.exe -- out\Debug\pdfium_unittests.exe
-
-  * Running pdfium_tests with Dr. Memory:
-    tools\drmemory\unpaced\bin\drmemory.exe -- out\Debug\pdfium_tests.exe --png YourInputPDF.pdf
-
-### Run test suite with Dr. Memory
-
-A set of scripts are provided to run PDFium test suite with Dr. Memory
-on buildbots, which can also be used for running test suite locally.
-
-  * Running pdfium_unittests with Dr. Memory:
-    tools\drmemory\scripts\pdfium_tests.bat -t pdfium_unittests
-
-  * Running pixel test suite with Dr. Memory:
-    tools\drmemory\scripts\pdfium_tests.bat -t pdfium_pixel
-
-## Documentation
-
-Command 'drmemory.exe -help' prints a list of Dr. Memory runtime
-options with short description.
-
-To view the full documention, point your web browser at
