+/**
+ * Deprecation Scanner tool. Loads API deprecation information from the

+ *
+ * TODO:
+ *  - audit error handling throughout, but mainly in scan package
+ *  - handling of covariant overrides
+ *  - handling of override of method found in multiple superinterfaces
+ *  - convert type/method/field output to Java source like syntax, e.g.
+ *      instead of java/lang/Runtime.runFinalizersOnExit(Z)V
+ *      print void java.lang.Runtime.runFinalizersOnExit(boolean)
+ *  - more example output in man page
+ *  - more rigorous GNU style option parsing; use joptsimple?
+ *
+ * FUTURES:
+ *  - add module support: -addmods, -modulepath, module arg
+ *  - load deprecation declarations from a designated class library instead
+ *    of the JDK
+ *  - load deprecation declarations from a module
+ *  - scan a module (but a modular jar can be treated just a like an ordinary jar)
+ *  - multi-version jar

+JDeprScan Internals
+-----
+
+**EXPERIMENTAL OPTIONS**
+
+    --Xload-class CLASSNAME
+
+        Loads deprecation data from the class named CLASSNAME instead of from
+        the JDK image.
+
+    --Xload-csv CVSFILE
+
+        Loads deprecation data from file CSVFILE.
+
+    --Xload-dir DIR
+
+        Loads deprecation data from the class hierarchy rooted
+        at the directory named DIR.
+
+    --Xload-jar JARFILE
+
+        Loads deprecation data from the classes contained in the
+        jar file named JARFILE.
+
+    --Xload-jdk9 JAVA_HOME
+
+        Loads deprecation data from a modular JDK whose home
+        directory is at JAVA_HOME. This essentially adds the given
+        path to the system-modules location.
+
+    --Xload-old-jdk JAVA_HOME
+
+        Loads deprecation data from an old (non-modular) JDK whose
+        home directory is at JAVA_HOME. This essentially scans the
+        rt.jar file from that JDK.
+
+    --Xload-self
+
+        Loads deprecation data from the running JDK image by
+        traversing the entire jrt: filesystem. This differs from
+        -release 9, which traverses modules, packages, and classes by
+        starting from a set of root modules and using javax.lang.model
+        mechanisms (as opposed to filesystem mechanisms) for
+        traversing contained elements recursively.
+
+    --Xcompiler-arg ARG
+
+        Adds ARG to the list of arguments passed to the compiler.
+
+    --Xcsv-comment COMMENT
+
+        Adds a comment line containing COMMENT to the top of the CSV
+        that is emitted.  Valid only when --Xprint-csv is
+        specified. More than one --Xcsv-comment option is permitted,
+        which will cause a corresponding number of comment lines to be
+        emitted to the CSV file.
+
+    --Xprint-csv
+
+        Prints out the loaded deprecation information in CSV format
+        to standard output. In this mode, no scanning is done, so
+        there must not be any additional directory, jar, or classname
+        arguments.
+
+**CSV FILE SYNTAX**
+
+The `-Xprint-csv` option causes **jdeprscan** to emit the loaded
+deprecation data in CSV (comma-separated value) format.  The general
+syntax of CSV is documented in [RFC 4180][RFC] with supplemental
+information in a [Wikipedia article][wiki].
+
+The file is encoded in UTF-8.
+
+The file consists of a series of lines. Any of the standard line
+separators CR (U+000D), LF (U+000A), or a CR immediately followed by
+LF, are supported. Newlines are only supported between records and
+are not supported within field values.
+
+Comment lines start with a `#` (U+0023) character in the first
+column. The entire line is ignored up until the next line separator
+sequence.
+
+Each line is divided into fields separated by the comma `,` (U+002C)
+character.  Horizontal whitespace is not treated specially; that is,
+it is considered part of a field's value. An empty line is considered
+to have one field which is the empty string.
+
+A field value that contains a comma or a quote quotation mark `"`
+(U+0022) must be surrounded by quotation marks. The surrounding
+quotation marks are not considered part of the field value. Any
+quotation marks that are part of a field value must be repeated in
+addition to being surrounded by quotation marks.
+
+It is a syntax error if a quotation mark appears within an unquoted field;
+if a quoted field isn't immediately followed by a comma or line
+separator; or if a quoted field is left unclosed at the end of the line.
+
+For example, a record with the following four fields:
+
+1. abcd
+2. ef,gh
+3. ij"kl
+4. mnop
+
+would be encoded as follows:
+
+        abcd,"ef,gh","ij""kl",mnop
+
+**CSV FILE DATA**
+
+The first line of output must be the following:
+
+        #jdepr1
+
+This is strictly a comment line, but it serves as a file
+identifier. The "1" indicates version 1 of this file.
+
+Zero or more comment lines follow, containing text that is specified
+by the `-Xcsv-comment` options.
+
+Subsequent non-comment lines must have the following five fields:
+
+        kind,typeName,descOrName,since,forRemoval
+
+Fields are defined as follows:
+
+ * _kind_ - one of CONSTRUCTOR, FIELD, METHOD, ENUM\_CONSTANT,
+   CLASS, INTERFACE, ENUM, or ANNOTATION\_TYPE. These correspond to
+   enumeration constants from the `javax.lang.model.element.ElementKind`
+   enum.
+
+ * _typeName_ - the fully qualified name of the type (if *kind* is
+   CLASS, INTERFACE, ENUM, or ANNOTATION\_TYPE) or of the enclosing
+   type (if _kind_ is CONSTRUCTOR, FIELD, METHOD, or
+   ENUM\_CONSTANT). This value is a _binary name_ [JLS 13.1][jls131]
+   using a slash character `/` (U+002F) to separate package and
+   top-level name components, and a dollar sign `$` (U+0024) to
+   separate nested name components. For example, the `Thread.State`
+   enum that appears in Java SE would have the following typeName:
+
+            java/lang/Thread$State
+
+ * _descOrName_ - if _kind_ is METHOD or CONSTRUCTOR, this is the method's
+   or constructor's descriptor [JVMS 4.3.3][jvms433]; if _kind_ is FIELD or
+   ENUM\_CONSTANT, this is its name; otherwise this field is empty.
+   A method's descriptor includes its name, parameter types, and return
+   type. For example, the method
+
+           public void String.getBytes(int srcBegin,
+                                       int srcEnd,
+                                       byte[] dst,
+                                       int dstBegin)
+
+   has the descriptor
+
+           getBytes(II[BI)V
+
+ * _since_ - the value of the `since` element of the `@Deprecated`
+   annotation, or empty if this element is not present.
+
+ * _forRemoval_ - the value of the `forRemoval` element of the
+   `@Deprecated` annotation, a boolean, either "true" or "false".
+
+Note that the _since_ field can have arbitrary text (excluding
+line separators) and is thus subject to quoting.
+
+**EXAMPLE OUTPUT**
+
+Given the following method declaration and annotation from the
+`java.lang.Runtime` class,
+
+            @Deprecated(since="1.2",
+                        forRemoval=true)
+            public static void runFinalizersOnExit(boolean value)
+
+the following line will be emitted from **jdeprscan -Xprint-csv**:
+
+            METHOD,java/lang/Runtime,runFinalizersOnExit(Z)V,1.2,true

+
+**DESCRIPTION**
+
+**jdeprscan** scans a class library for uses of deprecated APIs.
+**jdeprscan** processes one or more arguments, which can be any
+combination of a directory, a jar file, or a class name.
+
+A directory argument must specify a path to a directory hierarchy that
+reflects the Java package hierarchy of the classes it contains.
+**jdeprscan** will scan each class found in the directory hierarchy
+and report information about how those classes use deprecated APIs.
+
+Given a jar file, **jdeprscan** will scan the classes found within
+that jar file and report information about how those classes use
+deprecated APIs.
+
+Given a class name, **jdeprscan** will search for that class on the
+classpath, scan that class, and report information about how that
+class uses deprecated APIs. The class name must use the fully
+qualified binary name of the class, as described in the
+[Java Language Specification, section 13.1][jls131]. This form uses
+the '$' character instead of '.' as the separator for nested class names.
+For example, the `Thread.State` enum would be specified using the string
+
+        java.lang.Thread$State
+
+The `--class-path` and `-cp` options specify the classpath used for
+class searching. The classpath is used for classes named on the
+command line, as well as for dependencies of the classes in jar file
+or directory hierarchy to be scanned.
+
+The `--for-removal` option limits output to uses of deprecated APIs
+whose `@Deprecated` annotation includes the `forRemoval` element with
+the value `true`. Note: the `forRemoval` attribute of the
+`@Deprecated` annotation did not exist prior to Java SE 9, so this
+option cannot be used with a release value of 6, 7, or 8.
+
+The `--release` option specifies the Java SE specification version
+that determines the set of deprecated APIs for which scanning is
+done. This is useful if a deprecation report is desired that lists
+uses of deprecated APIs as of a particular release in the past. If no
+`--release` option is given, the latest release is used.
+
+The `--list` and `-l` options will list the known set of deprecated
+APIs instead of doing any scanning. Since no scanning is done,
+no directory, jar, or class arguments should be provided. The set
+of deprecated APIs listed is affected by the `--release` and the
+`--for-removal` options.
+
+
+**EXAMPLE OUTPUT**
+
+The output is a report that lists program elements that use deprecated
+APIs. Output is subject to change.
+
+Consider the following declarations from Java SE 9:
+
+        // java.lang.Boolean
+
+        @Deprecated(since="9")
+        public Boolean(boolean value)
+
+        // java.lang.Runtime
+
+        @Deprecated(since="1.2", forRemoval=true)
+        public static void runFinalizersOnExit(boolean value)
+
+Running **jdeprscan** over a class that calls these methods will result
+in output something like the following:
+
+        class Example uses method java/lang/Boolean.<init>(Z)V deprecated
+        class Example uses method java/lang/Runtime.runFinalizersOnExit(Z)V deprecated for removal
+
+Running **jdeprscan** with the `--list` option will result in output
+including something like the following:
+
+        ...
+        @Deprecated(since="9") java.lang.Boolean(boolean)
+        @Deprecated(since="1.2", forRemoval=true) void java.lang.Runtime.runFinalizersOnExit(boolean)
+        ...
+
+**NOTES**
+
+The **jdeprscan** tool operates by opening Java class files and
+reading their structures directly, particularly the constant
+pool. Because of this, **jdeprscan** can tell _that_ a deprecated API
+is used, but it often cannot tell _where_ in the class that API is
+used.
+
+The **jdeprscan** tool doesn't follow the same set of rules for
+emitting warnings as specified for Java compilers in [JLS section
+9.6.4.6][jls9646]. In particular, **jdeprscan** does not respond to
+the `@SuppressWarnings` annotation, as that is significant only in
+source code, not in class files. In addition, **jdeprscan** emits
+warnings even if the usage is within the API element that is
+deprecated and when the use and declaration are within the same
+outermost class.
