-Prerequisites
-=============
-
-You can use your Ubuntu box (>= 8.04. 9.10 is recommended) to test OTS library.
-
-First, install TrueType and OpenType fonts to the Ubuntu box as many as
-possible.
-
-    % sudo apt-get install ttf-.*[^0]$
-
-Then, put malicious TrueType fonts on `~/malicious/`. For details, please check
-http://code.google.com/p/chromium/issues/detail?id=27139#c2. Currently access
-to the issue is limited to chromium-security team members for security reasons.
-
-    % cd
-    % tar xjf ~/ttf-testsuite.tar.bz2
-
-Test
-====
-
-In order to verify that:
-
-1. OTS does not reject these unmalicious fonts.
-2. and transcoded fonts OTS generates can be loaded by a system font renderer (FreeType2).
-
-Run `test_unmalicious_fonts.sh` script:
-
-    % cd /path/to/ots/tests
-    % ./test_unmalicious_fonts.sh
-    ...............................................  (verify that no FAIL: is displayed)
-
-Then in order to verify that:
-
-1. OTS can reject malicious fonts
-2. or transcoded fonts generated by OTS do not crash a system font renderer (FreeType2).
-
-Run `test_malicious_fonts.sh` script:
-
-    % cd /path/to/ots/tests
-    % ./test_malicious_fonts.sh
-    ...............................................  (verify that no FAIL: is displayed)
-
-Command line tools
-==================
-
-We have some command line tools for tests. To build them:
-
-- On Linux:
-
-        % gyp --depth=. -f make ots-standalone.gyp
-        % make
-        (tool is located at build/Default directory)
-
-- On Windows (VC++ is needed):
-
-        % gyp --depth=. -f msvs ots-standalone.gyp
-        % devenv.exe /build Default ots-standalone.sln /project idempotent.vcproj
-        (tool is located at Default directory)
-
-- On Mac (XCode is needed):
-
-        % gyp --depth=. -f xcode ots-standalone.gyp
-        % xcodebuild -configuration Default -project ots-standalone.xcodeproj -target All
-        (tool is located at build/Default directory)
-
-You can use `idempotent` tool to check whether a font will be rejected or not.
-You can also use `ot-sanitise` tool to get sanitised font (it is available on
-Linux for now). See README file in the test directory for more details.
