 Description:
 
 This copy of NSS has been customized for Chromium.  NSPR is also put here
 rather than in a separate directory to emphasize the fact that Chromium is
 using NSPR strictly as an NSS dependency.
 
 We took a subset of NSS, omitting the SSL and SMIME libraries and the
 built-in root CA certificates module.  This NSS subset satisfies the
 dependencies of the NSS SSL library in src/net/third_party/nss.  Do NOT use
 this copy of NSS on platforms that have NSS as system libraries, such as
 Linux.
 
 The source code was checked out from the mozilla.org CVS repository using
 the nspr-checkout.sh and nss-checkout.sh scripts in the scripts directory.
-The current source code was checked out with the CVS tags -r NSS_3_12_6_RTM
-and -r NSPR_4_8_4_RTM.

 Local Modifications:
 
 We made the following local changes to NSPR.
 - patches/nspr-static.patch: to build NSPR as static libraries.  See NSPR
   bug 533014 (https://bugzilla.mozilla.org/show_bug.cgi?id=533014).
 - patches/prcpucfg.h: added to the mozilla/nsprpub/pr/include directory.
 - patches/nspr-attach-as-system-thread.patch: attach a "foreign" thread
   (a thread not created by NSPR) to NSPR as a "system" thread rather than
   a "user" thread, which needs to terminate before PR_Cleanup can return.
   (The "system" vs. "user" thread distinction comes from Java, and
   ultimately from Solaris threads.)  This is a workaround for
   http://crbug.com/40663.
-- patches/nspr-private-extern.patch: add .private_extern directives to NSPR
-  assembly code functions for Mac OS X.  See NSPR bug 568600
-  (https://bugzilla.mozilla.org/show_bug.cgi?id=568600).
-- patches/nspr-remove-flat-carbon-headers.patch: remove FlatCarbon headers
-  in prlink.c.  See NSPR bug 546478
-  (https://bugzilla.mozilla.org/show_bug.cgi?id=546478).
 
 We made the following local changes to NSS.
 - patches/nss-static.patch: to build NSS as static libraries and omit
   libpkix (the new certification path validation library) and
   softoken/legacydb (support for the old Berkeley DB databases).  See NSS
   bug 534471 (https://bugzilla.mozilla.org/show_bug.cgi?id=534471).
