This is the SQLite extension for Tcl using the Tcl Extension
Architecture (TEA).  For additional information on SQLite see

        http://www.sqlite.org/


UNIX BUILD
==========

Building under most UNIX systems is easy, just run the configure script
and then run make. For more information about the build process, see
the tcl/unix/README file in the Tcl src dist. The following minimal
example will install the extension in the /opt/tcl directory.

	$ cd sqlite-*-tea
	$ ./configure --prefix=/opt/tcl
	$ make
	$ make install

WINDOWS BUILD
=============

The recommended method to build extensions under windows is to use the
Msys + Mingw build process. This provides a Unix-style build while
generating native Windows binaries. Using the Msys + Mingw build tools
means that you can use the same configure script as per the Unix build
to create a Makefile. See the tcl/win/README file for the URL of
the Msys + Mingw download.

If you have VC++ then you may wish to use the files in the win
subdirectory and build the extension using just VC++. These files have
been designed to be as generic as possible but will require some
additional maintenance by the project developer to synchronise with
the TEA configure.in and Makefile.in files. Instructions for using the
VC++ makefile are written in the first part of the Makefile.vc
file.

puts {
Page size in bytes

    The number of bytes in a single page of the database file.  
    Usually 1024.

Number of pages in the whole file
}
puts "    The number of $pageSize-byte pages that go into forming the complete
    database"
puts {
Pages that store data

    The number of pages that store data, either as primary B*Tree pages or
    as overflow pages.  The number at the right is the data pages divided by
    the total number of pages in the file.

Pages on the freelist

    The number of pages that are not currently in use but are reserved for
    future use.  The percentage at the right is the number of freelist pages
    divided by the total number of pages in the file.

Pages of auto-vacuum overhead

    The number of pages that store data used by the database to facilitate
    auto-vacuum. This is zero for databases that do not support auto-vacuum.

Number of tables in the database

    The number of tables in the database, including the SQLITE_MASTER table
    used to store schema information.

Number of indices

    The total number of indices in the database.

Number of defined indices

    The number of indices created using an explicit CREATE INDEX statement.

Number of implied indices

    The number of indices used to implement PRIMARY KEY or UNIQUE constraints
    on tables.

Size of the file in bytes

    The total amount of disk space used by the entire database files.

Bytes of user payload stored

    The total number of bytes of user payload stored in the database. The
    schema information in the SQLITE_MASTER table is not counted when
    computing this number.  The percentage at the right shows the payload
    divided by the total file size.

Percentage of total database

    The amount of the complete database file that is devoted to storing
    information described by this category.

Number of entries

    The total number of B-Tree key/value pairs stored under this category.

Bytes of storage consumed

    The total amount of disk space required to store all B-Tree entries
    under this category.  The is the total number of pages used times
    the pages size.

Bytes of payload

    The amount of payload stored under this category.  Payload is the data
    part of table entries and the key part of index entries.  The percentage
    at the right is the bytes of payload divided by the bytes of storage 
    consumed.

Bytes of metadata

    The amount of formatting and structural information stored in the
    table or index.  Metadata includes the btree page header, the cell pointer
    array, the size field for each cell, the left child pointer or non-leaf
    cells, the overflow pointers for overflow cells, and the rowid value for
    rowid table cells.  In other words, metadata is everything that is neither
    unused space nor content.  The record header in the payload is counted as
    content, not metadata.

Average payload per entry

    The average amount of payload on each entry.  This is just the bytes of
    payload divided by the number of entries.

Average unused bytes per entry

    The average amount of free space remaining on all pages under this
    category on a per-entry basis.  This is the number of unused bytes on
    all pages divided by the number of entries.

Non-sequential pages

    The number of pages in the table or index that are out of sequence.
    Many filesystems are optimized for sequential file access so a small
    number of non-sequential pages might result in faster queries,
    especially for larger database files that do not fit in the disk cache.
    Note that after running VACUUM, the root page of each table or index is
    at the beginning of the database file and all other pages are in a
    separate part of the database file, resulting in a single non-
    sequential page.

Maximum payload per entry

    The largest payload size of any entry.

Entries that use overflow

    The number of entries that user one or more overflow pages.

Total pages used

    This is the number of pages used to hold all information in the current
    category.  This is the sum of index, primary, and overflow pages.

Index pages used

    This is the number of pages in a table B-tree that hold only key (rowid)
    information and no data.

Primary pages used

    This is the number of B-tree pages that hold both key and data.

Overflow pages used

    The total number of overflow pages used for this category.

Unused bytes on index pages

    The total number of bytes of unused space on all index pages.  The
    percentage at the right is the number of unused bytes divided by the
    total number of bytes on index pages.

Unused bytes on primary pages

    The total number of bytes of unused space on all primary pages.  The
    percentage at the right is the number of unused bytes divided by the
    total number of bytes on primary pages.

Unused bytes on overflow pages

    The total number of bytes of unused space on all overflow pages.  The
    percentage at the right is the number of unused bytes divided by the
    total number of bytes on overflow pages.

Unused bytes on all pages

    The total number of bytes of unused space on all primary and overflow 
    pages.  The percentage at the right is the number of unused bytes 
    divided by the total number of bytes.

 *
 * These classes are inspired by
 * - std::auto_ptr
 * - boost::scoped_ptr & boost::scoped_array
 * - Taligent Safe Pointers (TOnlyPointerTo)
 *
 * but none of those provide for all of the goals for ICU smart pointers:
 * - Smart pointer owns the object and releases it when it goes out of scope.
 * - No transfer of ownership via copy/assignment to reduce misuse. Simpler & more robust.
 * - ICU-compatible: No exceptions.
 * - Need to be able to orphan/release the pointer and its ownership.
 * - Need variants for normal C++ object pointers, C++ arrays, and ICU C service objects.
 *
 * For details see http://site.icu-project.org/design/cpp/scoped_ptr

 * As a temporary workaround, you can add an explicit <code>#define</code> for some macros
 * before it is first tested, or add an equivalent -D macro definition
 * to the compiler's command line.
 *
 * Note: Some compilers provide ways to show the predefined macros.
 * For example, with gcc you can compile an empty .c file and have the compiler
 * print the predefined macros with
 * \code
 * gcc -E -dM -x c /dev/null | sort

 * \brief C API: BreakIterator
 *
 * <h2> BreakIterator C API </h2>
 *
 * The BreakIterator C API defines  methods for finding the location
 * of boundaries in text. Pointer to a UBreakIterator maintain a
 * current position and scan over text returning the index of characters
 * where boundaries occur.
 * <p>
 * Line boundary analysis determines where a text string can be broken
 * when line-wrapping. The mechanism correctly handles punctuation and
 * hyphenated words.
 * <p>
 * Sentence boundary analysis allows selection with correct
 * interpretation of periods within numbers and abbreviations, and
 * trailing punctuation marks such as quotation marks and parentheses.
 * <p>
 * Word boundary analysis is used by search and replace functions, as
 * well as within text editing applications that allow the user to
 * select words with a double click. Word selection provides correct
 * interpretation of punctuation marks within and following
 * words. Characters that are not part of a word, such as symbols or
 * punctuation marks, have word-breaks on both sides.
 * <p>
 * Character boundary analysis identifies the boundaries of
 * "Extended Grapheme Clusters", which are groupings of codepoints
 * that should be treated as character-like units for many text operations.
 * Please see Unicode Standard Annex #29, Unicode Text Segmentation,
 * http://www.unicode.org/reports/tr29/ for additional information 
 * on grapheme clusters and guidelines on their use.
 * <p>
 * Title boundary analysis locates all positions,
 * typically starts of words, that should be set to Title Case
 * when title casing the text.
 * <p>
 * The text boundary positions are found according to the rules
 * described in Unicode Standard Annex #29, Text Boundaries, and
 * Unicode Standard Annex #14, Line Breaking Properties.  These
 * are available at http://www.unicode.org/reports/tr14/ and
 * http://www.unicode.org/reports/tr29/.
 * <p>
 * In addition to the plain C API defined in this header file, an
 * object oriented C++ API with equivalent functionality is defined in the
 * file brkiter.h.
 * <p>
 * Code snippets illustrating the use of the Break Iterator APIs
 * are available in the ICU User Guide,
 * http://icu-project.org/userguide/boundaryAnalysis.html
 * and in the sample program icu/source/samples/break/break.cpp

/**
 * \file
 * \brief C API: Unicode Properties
 *
 * This C API provides low-level access to the Unicode Character Database.
 * In addition to raw property values, some convenience functions calculate
 * derived properties, for example for Java-style programming.
 *
 * Unicode assigns each code point (not just assigned character) values for
 * many properties.
 * Most of them are simple boolean flags, or constants from a small enumerated list.
 * For some properties, values are strings or other relatively more complex types.
 *
 * For more information see
 * "About the Unicode Character Database" (http://www.unicode.org/ucd/)
 * and the ICU User Guide chapter on Properties (http://icu-project.org/userguide/properties.html).
 *
 * Many functions are designed to match java.lang.Character functions.
 * See the individual function documentation,
 * and see the JDK 1.4 java.lang.Character documentation
 * at http://java.sun.com/j2se/1.4/docs/api/java/lang/Character.html
 *
 * There are also functions that provide easy migration from C/POSIX functions
 * like isblank(). Their use is generally discouraged because the C/POSIX
 * standards do not define their semantics beyond the ASCII range, which means
 * that different implementations exhibit very different behavior.
 * Instead, Unicode properties should be used directly.
 *
 * There are also only a few, broad C/POSIX character classes, and they tend
 * to be used for conflicting purposes. For example, the "isalpha()" class
 * is sometimes used to determine word boundaries, while a more sophisticated
 * approach would at least distinguish initial letters from continuation
 * characters (the latter including combining marks).
 * (In ICU, BreakIterator is the most sophisticated API for word boundaries.)
 * Another example: There is no "istitle()" class for titlecase characters.
 *
 * ICU 3.4 and later provides API access for all twelve C/POSIX character classes.
 * ICU implements them according to the Standard Recommendations in
 * Annex C: Compatibility Properties of UTS #18 Unicode Regular Expressions
 * (http://www.unicode.org/reports/tr18/#Compatibility_Properties).
 *
 * API access for C/POSIX character classes is as follows:
 * - alpha:     u_isUAlphabetic(c) or u_hasBinaryProperty(c, UCHAR_ALPHABETIC)
 * - lower:     u_isULowercase(c) or u_hasBinaryProperty(c, UCHAR_LOWERCASE)
 * - upper:     u_isUUppercase(c) or u_hasBinaryProperty(c, UCHAR_UPPERCASE)
 * - punct:     u_ispunct(c)
 * - digit:     u_isdigit(c) or u_charType(c)==U_DECIMAL_DIGIT_NUMBER
 * - xdigit:    u_isxdigit(c) or u_hasBinaryProperty(c, UCHAR_POSIX_XDIGIT)
 * - alnum:     u_hasBinaryProperty(c, UCHAR_POSIX_ALNUM)
 * - space:     u_isUWhiteSpace(c) or u_hasBinaryProperty(c, UCHAR_WHITE_SPACE)
 * - blank:     u_isblank(c) or u_hasBinaryProperty(c, UCHAR_POSIX_BLANK)
 * - cntrl:     u_charType(c)==U_CONTROL_CHAR
 * - graph:     u_hasBinaryProperty(c, UCHAR_POSIX_GRAPH)
 * - print:     u_hasBinaryProperty(c, UCHAR_POSIX_PRINT)
 *
 * Note: Some of the u_isxyz() functions in uchar.h predate, and do not match,
 * the Standard Recommendations in UTS #18. Instead, they match Java
 * functions according to their API documentation.
 *
 * \htmlonly
 * The C/POSIX character classes are also available in UnicodeSet patterns,
 * using patterns like [:graph:] or \p{graph}.
 * \endhtmlonly
 *
 * Note: There are several ICU whitespace functions.
 * Comparison:
 * - u_isUWhiteSpace=UCHAR_WHITE_SPACE: Unicode White_Space property;
 *       most of general categories "Z" (separators) + most whitespace ISO controls
 *       (including no-break spaces, but excluding IS1..IS4 and ZWSP)
 * - u_isWhitespace: Java isWhitespace; Z + whitespace ISO controls but excluding no-break spaces
 * - u_isJavaSpaceChar: Java isSpaceChar; just Z (including no-break spaces)
 * - u_isspace: Z + whitespace ISO controls (including no-break spaces)
 * - u_isblank: "horizontal spaces" = TAB + Zs - ZWSP

 *
 * <h2> Collator C API </h2>
 *
 * The C API for Collator performs locale-sensitive
 * string comparison. You use this service to build
 * searching and sorting routines for natural language text.
 * <p>
 * For more information about the collation service see 
 * <a href="http://userguide.icu-project.org/collation">the User Guide</a>.
 * <p>
 * Collation service provides correct sorting orders for most locales supported in ICU. 
 * If specific data for a locale is not available, the orders eventually falls back
 * to the <a href="http://www.unicode.org/reports/tr35/tr35-collation.html#Root_Collation">CLDR root sort order</a>. 
 * <p>
 * Sort ordering may be customized by providing your own set of rules. For more on
 * this subject see the <a href="http://userguide.icu-project.org/collation/customization">
 * Collation Customization</a> section of the User Guide.
 * <p>
 * @see         UCollationResult
 * @see         UNormalizationMode

 *
 * Miscellaneous switches:
 *
 * A number of macros affect a variety of minor aspects of ICU.
 * Most of them used to be defined elsewhere (e.g., in utypes.h or platform.h)
 * and moved here to make them easier to find.
 *
 * Switches for excluding parts of ICU library code modules:
 *
 * Changing these macros allows building partial, smaller libraries for special purposes.
 * By default, all modules are built.
 * The switches are fairly coarse, controlling large modules.
 * Basic services cannot be turned off.
 *
 * Building with any of these options does not guarantee that the
 * ICU build process will completely work. It is recommended that
 * the ICU libraries and data be built using the normal build.
 * At that time you should remove the data used by those services.
 * After building the ICU data library, you should rebuild the ICU
 * libraries with these switches customized to your needs.
