=head1 NAME
bbcolors - Save and load text color sets for BBEdit.
=head1 SYNOPSIS
bbcolors -save "scheme name"
bbcolors -load "scheme name"
bbcolors -man
=head1 DESCRIPTION
B<bbcolors> saves and loads "sets" of text color preferences for BBEdit.
=head1 OPTIONS
=over 8
=item B<-delete> F<setname>
Delete the saved bbcolors scheme named 'setname'. Does not effect current BBEdit preferences.
=item B<-list>
List all color sets.
=item B<-load> F<setname>
Replace current BBEdit text colors with scheme named "setname".
=item B<-save> F<setname>
Save current BBEdit text colors to scheme named "setname', overwriting any existing scheme with that name.
=item B<-zap>
Deletes all current BBEdit (or TextWrangler) color settings, including those keyed to specific languages. For example, if you set custom colors for the Perl language in BBEdit, and then use bbcolors to load a new colorset that does not contain Perl-specific colors, your previously-set custom colors for Perl will remain in place. If you use the B<-zap> option when loading the new scheme, however, your custom color settings will be deleted, and your Perl files will be displayed using the default colors of the just-loaded color scheme.
=item B<-lang> F<"language name">
Target a specific language when saving, loading, or zapping.
=over 4
=item *
If saving, only save those colors set for the specified language. (The <-save> command normally saves all colors.)
=item *
If loading, only load those colors from the named scheme which are keyed to the specified language.
=item *
If zapping, only zap the preferences keyed to the specified language.
=back
=item B<-open>
Open the ~/Library/Application Support/BBColors/ folder in the Finder. If the folder doesn't exist, it will be created.
=item B<-bbopen>
Open the ~/Library/Application Support/BBColors/ folder in a new disk browser window using BBEdit (or TextWrangler, if used in conjunction with the B<-tw> option). If the folder doesn't exist, it will be created.
=item B<-bbedit>
Explicitly use with BBEdit (as opposed to TextWrangler). This option is on by default.
=item B<-textwrangler>
=item B<-tw>
Use TextWrangler instead of BBEdit.
=item B<-help>
Print a brief help message and exit.
=item B<-man>
Print the full bbcolors manual page.
=item B<-version>
Print the current bbcolors version number.
=back
=head1 A NOTE ON TEXT ENCODING
B<bbcolors> should work just fine with languages modules and saved color sets whose names contain non-ASCII characters. The only provision is that all input and output is assumed to be UTF-8.
=head1 VERSION HISTORY
=over 8
=item 1.0.1 - Sun 15 Oct 2006
Switched to a more efficient method of testing whether BBEdit and TextWrangler are currently running. Cleaned up the documentation slightly, replacing several instances of "color set" with "color scheme".
