const ABOUT: &'static str = "
ucd-generate is a tool that generates Rust source files containing various
Unicode tables.
Unicode tables are typically represented by a sorted sequence of character
ranges, which can be searched quickly via binary search. There is also support
for generating FSTs (slower access but better compression for things like
character names), and tries (faster access, but sometimes bigger than sorted
ranges).
Project home page: https://github.com/BurntSushi/ucd-generate";
const ABOUT_BIDI_CLASS: &'static str = "\
bidi-class produces one table of Unicode codepoint ranges for each
possible Bidi_Class value.
";
const ABOUT_CANONICAL_COMBINING_CLASS: &'static str = "\
canonical-combining-class produces one table of Unicode codepoint ranges for
each possible Canonical_Combining_Class value.
";
const ABOUT_GENERAL_CATEGORY: &'static str = "\
general-category produces one table of Unicode codepoint ranges for each
possible General_Category value.
";
const ABOUT_SCRIPT: &'static str = "\
script produces one table of Unicode codepoint ranges for each possible Script
value.
";
const ABOUT_SCRIPT_EXTENSION: &'static str = "\
script-extension produces one table of Unicode codepoint ranges for each
possible Script_Extension value.
";
const ABOUT_JOINING_TYPE: &'static str = "\
joining-type produces one table of Unicode codepoint ranges for each
possible Joining_Type value.
";
const ABOUT_AGE: &'static str = "\
age produces a table for each discrete Unicode age. Each table includes the
codepoints that were added for that age. Tables can be emitted as a sorted
sequence of ranges, an FST or a trie.
";
const ABOUT_BIDI_MIRRORING_GLYPH: &'static str = "\
bidi-mirroring-glyph produces a table that maps codepoints that have the
Bidi_Mirrored=Yes property to another codepoint that typically has a glyph that
is the mirror image of the original codepoint's glyph.
";
const ABOUT_PROP_BOOL: &'static str = "\
property-bool produces possibly many tables for boolean properties. Tables can
be emitted as a sorted sequence of ranges, an FST or a trie.
";
const ABOUT_PERL_WORD: &'static str = "\
perl-word emits a table of codepoints in Unicode's definition of the \\w
character class, according to Annex C in UTS#18. In particular, this includes
the Alphabetic and Join_Control properties, in addition to the Decimal_Number,
Mark and Connector_Punctuation general categories.
Commands for \\s and \\d are not provided, since they directly correspond
to the property Whitespace and the general category Decimal_Number,
respectively.
The flags for this command are similar as the flags for property-bool.
";
const ABOUT_JAMO_SHORT_NAME: &'static str = "\
jamo-short-name parses the UCD's Jamo.txt file and emits its contents as a
slice table. The slice consists of a sorted sequences of pairs, where each
pair corresponds to the codepoint and the Jamo_Short_Name property value.
When emitted as an FST table, the FST corresponds to a map from a Unicode
codepoint (encoded as a big-endian u32) to a u64, where the u64 contains the
Jamo_Short_Name property value. The value is encoded in the least significant
bytes (up to 3).
Since the table is so small, the slice table is faster to search.
";
const ABOUT_NAMES: &'static str = "\
names emits a table of all character names in the UCD, including aliases and
names that are algorithmically generated such as Hangul syllables and
ideographs. Flags can be provided to tweak this behavior.
This table maps character names to codepoints.
";
const ABOUT_TEST_UNICODE_DATA: &'static str = "\
test-unicode-data parses the UCD's UnicodeData.txt file and emits its contents
on stdout. The purpose of this command is to diff the output with the input and
confirm that they are identical. This is a sanity test on the UnicodeData.txt
parser.
";
const ABOUT_PROPERTY_NAMES: &'static str = "\
property-names emits a table of all property aliases that map to a canonical
property name.
";
const ABOUT_PROPERTY_VALUES: &'static str = "\
property-values emits a table of all property values and their aliases that map
to a canonical property value.
";
const ABOUT_CASE_FOLDING_SIMPLE: &'static str = "\
case-folding emits a table of Simple case folding mappings from codepoint
to codepoint. When codepoints are mapped according to this table, then case
differences (according to Unicode) are eliminated.
";
const ABOUT_CASE_MAPPING: &'static str = "\
case-mapping emits case mapping tables, which map from a codepoint to a
list of codepoints (currently up to three), and are used to convert
text between lower, upper, and title cases.
This command currently has no support for emitting the conditional case
mapping data, and can only produce the unconditional mapping tables.

grapheme-cluster-break emits the table of property values and their
corresponding codepoints for the Grapheme_Cluster_Break property.

word-break emits the table of property values and their corresponding
codepoints for the Word_Break property.
";

sentence-break emits the table of property values and their corresponding
codepoints for the Sentence_Break property.
";
const ABOUT_DFA: &'static str = "\
dfa emits a single serialized DFAs from an arbitrary regular expression. If
you want a regular expression for finding the start and end of a match, then
use the 'regex' sub-command. Otherwise, if you only care about the end of a
match (forward DFA, the default) or the start of a match (reverse DFA), then
only a single DFA is necessary.
