+=head1 NAME
+
+SQL::Abstract::Tree - Represent SQL as an AST
+
=head1 SYNOPSIS
my $sqla_tree = SQL::Abstract::Tree->new({ profile => 'console' });
my $sqla_tree = SQL::Abstract::Tree->new({ profile => 'console' });
+ $args = {
+ profile => 'console', # predefined profile to use (default: 'none')
+ fill_in_placeholders => 1, # true for placeholder population
+ placeholder_surround => # The strings that will be wrapped around
+ [GREEN, RESET], # populated placeholders if the above is set
+ indent_string => ' ', # the string used when indenting
+ indent_amount => 2, # how many of above string to use for a single
+ # indent level
+ newline => "\n", # string for newline
+ colormap => {
+ select => [RED, RESET], # a pair of strings defining what to surround
+ # the keyword with for colorization
+ # ...
+ },
+ indentmap => {
+ select => 0, # A zero means that the keyword will start on
+ # a new line
+ from => 1, # Any other positive integer means that after
+ on => 2, # said newline it will get that many indents
+ # ...
+ },
+ }
+
+Returns a new SQL::Abstract::Tree object. All arguments are optional.
+
+=head3 profiles
+
+There are four predefined profiles, C<none>, C<console>, C<console_monochrome>,
+and C<html>. Typically a user will probably just use C<console> or
+C<console_monochrome>, but if something about a profile bothers you, merely
+use the profile and override the parts that you don't like.
+
=head2 format
- $sqlat->format('SELECT * FROM bar')
+ $sqlat->format('SELECT * FROM bar WHERE x = ?', [1])
+
+Takes C<$sql> and C<\@bindargs>.
+
+Returns a formatting string based on the string passed in
+
+=head2 parse
+
+ $sqlat->parse('SELECT * FROM bar WHERE x = ?')
+
+Returns a "tree" representing passed in SQL. Please do not depend on the
+structure of the returned tree. It may be stable at some point, but not yet.
+
+=head2 unparse
+
+ $sqlat->parse($tree_structure, \@bindargs)
+
+Transform "tree" into SQL, applying various transforms on the way.
+
+=head2 format_keyword
+
+ $sqlat->format_keyword('SELECT')
+
+Currently this just takes a keyword and puts the C<colormap> stuff around it.
+Later on it may do more and allow for coderef based transforms.
+
+=head2 pad_keyword
+
+ my ($before, $after) = @{$sqlat->pad_keyword('SELECT')};
+
+Returns whitespace to be inserted around a keyword.
+
+=head2 fill_in_placeholder
+
+ my $value = $sqlat->fill_in_placeholder(\@bindargs)
+
+Removes last arg from passed arrayref and returns it, surrounded with
+the values in placeholder_surround, and then surrounded with single quotes.
+
+=head2 indent
+
+Returns as many indent strings as indent amounts times the first argument.
