+OPTIONS:
+
+ -analyze-headers
+ 
+   Also analyze functions in #included files.  By default, such functions
+   are skipped unless they are called by functions within the main source file.
+ 
+ -o <output location>
+  
+   Specifies the output directory for analyzer reports. Subdirectories will be
+   created as needed to represent separate "runs" of the analyzer. If this
+   option is not specified, a directory is created in /tmp (TMPDIR on Mac OS X)
+   to store the reports.
+
+ -h             
+ --help
+
+   Display this message.
+
+ -k
+ --keep-going
+				  
+   Add a "keep on going" option to the specified build command. This option
+   currently supports make and xcodebuild. This is a convenience option; one
+   can specify this behavior directly using build options.
+
+ --html-title [title]
+ --html-title=[title]
+
+   Specify the title used on generated HTML pages. If not specified, a default
+   title will be used.
+
+ -plist
+ 
+   By default the output of scan-build is a set of HTML files. This option
+   outputs the results as a set of .plist files.
+ 
+ -plist-html
+ 
+   By default the output of scan-build is a set of HTML files. This option
+   outputs the results as a set of HTML and .plist files.
+ 
+ --status-bugs
+ 
+   By default, the exit status of scan-build is the same as the executed build
+   command. Specifying this option causes the exit status of scan-build to be 1
+   if it found potential bugs and 0 otherwise.
+
+ --use-cc [compiler path]   
+ --use-cc=[compiler path]
+  
+   scan-build analyzes a project by interposing a "fake compiler", which
+   executes a real compiler for compilation and the static analyzer for analysis.
+   Because of the current implementation of interposition, scan-build does not
+   know what compiler your project normally uses.  Instead, it simply overrides
+   the CC environment variable, and guesses your default compiler.
+   
+   In the future, this interposition mechanism to be improved, but if you need
+   scan-build to use a specific compiler for *compilation* then you can use
+   this option to specify a path to that compiler.
+
+ --use-c++ [compiler path]
+ --use-c++=[compiler path]
+ 
+   This is the same as "-use-cc" but for C++ code.
+ 
+ -v
+ 
+   Enable verbose output from scan-build. A second and third '-v' increases
+   verbosity.
+
+ -V
+ --view
+
+   View analysis results in a web browser when the build completes.
+
+ADVANCED OPTIONS:
+
+ -no-failure-reports
+ 
+   Do not create a 'failures' subdirectory that includes analyzer crash reports
+   and preprocessed source files.
+
+ -stats
+ 
+   Generates visitation statistics for the project being analyzed.
+
+ -maxloop <loop count>
+ 
+   Specifiy the number of times a block can be visited before giving up.
+   Default is 4. Increase for more comprehensive coverage at a cost of speed.
+  
+ -internal-stats
+ 
+   Generate internal analyzer statistics.
+ 
+ --use-analyzer [Xcode|path to clang] 
+ --use-analyzer=[Xcode|path to clang]
+ 
+   scan-build uses the 'clang' executable relative to itself for static
+   analysis. One can override this behavior with this option by using the
+   'clang' packaged with Xcode (on OS X) or from the PATH.
+
+ --keep-empty
+
+   Don't remove the build results directory even if no issues were reported.
+
+ --override-compiler 
+   Always resort to the ccc-analyzer even when better interposition methods 
+   are available.
+   
+CONTROLLING CHECKERS:
+
+ A default group of checkers are always run unless explicitly disabled.
+ Checkers may be enabled/disabled using the following options:
+
+ -enable-checker [checker name]
+ -disable-checker [checker name]

+BUILD OPTIONS
+
+ You can specify any build option acceptable to the build command.
+
+EXAMPLE
+
+ scan-build -o /tmp/myhtmldir make -j4
+     
+The above example causes analysis reports to be deposited into a subdirectory
+of "/tmp/myhtmldir" and to run "make" with the "-j4" option. A different
+subdirectory is created each time scan-build analyzes a project. The analyzer
+should support most parallel builds, but not distributed builds.

+.Sh DESCRIPTION
+.Nm
+is a Perl script that invokes the Clang static analyzer.  Options used by
+.Nm
+or by the analyzer appear first, followed by the
+.Ar build_command
+and any
+.Ar build_options
+normally used to build the target system.
+.Pp
+The static analyzer employs a long list of checking algorithms, see
+.Sx CHECKERS .
+Output can be written in standard
+.Li .plist
+and/or HTML format.
+.Pp
+The following options are supported:
+.Bl -tag -width indent
+.It Fl analyze-headers
+Also analyze functions in #included files.
+.It Fl enable-checker Ar checker_name , Fl disable-checker Ar checker_name
+Enable/disable
+.Ar checker_name .
+See
+.Sx CHECKERS .
+.It Fl h , Fl Fl help
+Display this message.
+.It Fl Fl help-checkers
+List default checkers, see
+.Sx CHECKERS .
+.It Fl Fl html-title Ns Op = Ns Ar title
+Specify the title used on generated HTML pages.
+A default title is generated if
+.Ar title
+is not specified.
+.It Fl k , Fl Fl keep-going
+Add a
+.Dq keep on going
+option to
+.Ar build_command .
+Currently supports make and xcodebuild. This is a convenience option;
+one can specify this behavior directly using build options.
+.It Fl o
+Target directory for HTML report files.  Subdirectories will be
+created as needed to represent separate invocations
+of the analyzer.  If this option is not specified, a directory is
+created in /tmp (TMPDIR on Mac OS X) to store the reports.
+.It Fl plist
+Output the results as a set of
+.Li .plist
+files. (By default the output of
+.Nm
+is a set of HTML files.)
+.It Fl plist-html
+Output the results as a set of HTML and .plist files
+.It Fl Fl status-bugs
+Set exit status to 1 if it found potential bugs and 0 otherwise. By
+default the exit status of
+.Nm
+is that returned by
+.Ar build_command .
+.It Fl Fl use-c++ Ns Op = Ns Ar compiler_path
+Guess the default compiler for your C++ and Objective-C++ code. Use this
+option to specify an alternate compiler.
+.It Fl Fl use-cc Ns Op = Ns Ar compiler_path
+Guess the default compiler for your C and Objective-C code. Use this
+option to specify an alternate compiler.
+.It Fl v
+Verbose output from
+.Nm
+and the analyzer. A second and
+third
+.Ar v
+increases verbosity.
+.It Fl V , Fl Fl view
+View analysis results in a web browser when the build completes.
+.It Fl constraints Op Ar model
+Specify the contraint engine used by the analyzer.  By default the
+.Ql range
+model is used.  Specifying
+.Ql basic
+uses a simpler, less powerful constraint model used by checker-0.160
+and earlier.
+.It Fl maxloop Ar N
+Specifiy the number of times a block can be visited before giving
+up. Default is 4. Increase for more comprehensive coverage at a
+cost of speed.
+.It Fl no-failure-reports
+Do not create a
+.Ql failures
+subdirectory that includes analyzer crash reports and preprocessed
+source files.
+.It Fl stats
+Generates visitation statistics for the project being analyzed.
+.It Fl store Op Ar model
+Specify the store model used by the analyzer. By default, the
+.Ql region
+store model is used.
+.Ql region
+specifies a field-
+sensitive store model. Users can also specify
+.Ql basic
+which is far less precise but can more quickly analyze code.
+.Ql basic
+was the default store model for checker-0.221 and earlier.
+.\"
+.El
+.Sh EXIT STATUS
+.Nm
+returns the value returned by
+.Ar build_command
+unless
+.Fl Fl status-bugs
+or
+.Fl Fl keep-going
+is used.

+.Sh CHECKERS
+The checkers listed below may be enabled/disabled using the
+.Fl enable-checker
+and
+.Fl disable-checker
+options.
+A default group of checkers is run unless explicitly disabled.
+Exactly which checkers constitute the default group is a function
+of the operating system in use; they are listed with
+.Fl Fl help-checkers .
+.Bl -tag -width indent.
+.It core.AdjustedReturnValue
+Check to see if the return value of a function call is different than
+the caller expects (e.g., from calls through function pointers).
+.It core.AttributeNonNull
+Check for null pointers passed as arguments to a function whose arguments are marked with the
+.Ql nonnull
+attribute.
+.It core.CallAndMessage
+Check for logical errors for function calls and Objective-C message expressions (e.g., uninitialized arguments, null function pointers).
+.It core.DivideZero
+Check for division by zero.
+.It core.NullDereference
+Check for dereferences of null pointers.
+.It core.StackAddressEscape
+Check that addresses to stack memory do not escape the function.
+.It core.UndefinedBinaryOperatorResult
+Check for undefined results of binary operators.
