+Usage: ./phan [options] [files...]
+ -f, --file-list <filename>
+ A file containing a list of PHP files to be analyzed
+
+ -r, --file-list-only
+ A file containing a list of PHP files to be analyzed to the
+ exclusion of any other directories or files passed in. This
+ is useful when running Phan from a stored state file and
+ passing in a small subset of files to be re-analyzed.
+
+ -l, --directory <directory>
+ A directory to recursively read PHP files from to analyze
+
+ -3, --exclude-directory-list <dir_list>
+ A comma-separated list of directories for which any files
+ included from that directory will not be analysis. Note
+ that adding a directory here will not cause its files to
+ be parsed.
+
+ -d, --project-root-directory
+ Hunt for a directory named .phan in the current or parent
+ directory and read configuration file config.php from that
+ path.
+
+ -m <mode>, --output-mode
+ Output mode from 'text', 'json', 'codeclimate', or 'checkstyle'
+
+ -o, --output <filename>
+ Output filename
+
+ -p, --progress-bar
+ Show progress bar
+
+ -a, --dump-ast
+ Emit an AST for each file rather than analyze
+
+ -e, --expand-file-list
+ Expand the list of files passed in to include any files
+ that depend on elements defined in those files. This is
+ useful when running Phan from a state file and passing in
+ just the set of changed files.
+
+ -q, --quick
+ Quick mode - doesn't recurse into all function calls
+
+ -b, --backward-compatibility-checks
+ Check for potential PHP 5 -> PHP 7 BC issues
+
+ -i, --ignore-undeclared
+ Ignore undeclared functions and classes
+
+ -y, --minimum-severity <level in {0,5,10}>
+ Minimum severity level (low=0, normal=5, critical=10) to report.
+ Defaults to 0.
+
+ -c, --parent-constructor-required
+ Comma-separated list of classes that require
+ parent::__construct() to be called
+
+ -x, --dead-code-detection
+ Emit issues for classes, methods, functions, constants and
+ properties that are probably never referenced and can
+ possibly be removed.
+
+ -j, --processes <int>
+ The number of parallel processes to run during the analysis
+ phase. Defaults to 1.
+
+ -z, --signature-compatibility
+ Analyze signatures for methods that are overrides to ensure
+ compatiiblity with what they're overriding.
+
+ -h,--help
+ This help information</code></pre>
