-                   GNU LESSER GENERAL PUBLIC LICENSE
-                       Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-
-  This version of the GNU Lesser General Public License incorporates
-the terms and conditions of version 3 of the GNU General Public
-License, supplemented by the additional permissions listed below.
-
-  0. Additional Definitions.
-
-  As used herein, "this License" refers to version 3 of the GNU Lesser
-General Public License, and the "GNU GPL" refers to version 3 of the GNU
-General Public License.
-
-  "The Library" refers to a covered work governed by this License,
-other than an Application or a Combined Work as defined below.
-
-  An "Application" is any work that makes use of an interface provided
-by the Library, but which is not otherwise based on the Library.
-Defining a subclass of a class defined by the Library is deemed a mode
-of using an interface provided by the Library.
-
-  A "Combined Work" is a work produced by combining or linking an
-Application with the Library.  The particular version of the Library
-with which the Combined Work was made is also called the "Linked
-Version".
-
-  The "Minimal Corresponding Source" for a Combined Work means the
-Corresponding Source for the Combined Work, excluding any source code
-for portions of the Combined Work that, considered in isolation, are
-based on the Application, and not on the Linked Version.
-
-  The "Corresponding Application Code" for a Combined Work means the
-object code and/or source code for the Application, including any data
-and utility programs needed for reproducing the Combined Work from the
-Application, but excluding the System Libraries of the Combined Work.
-
-  1. Exception to Section 3 of the GNU GPL.
-
-  You may convey a covered work under sections 3 and 4 of this License
-without being bound by section 3 of the GNU GPL.
-
-  2. Conveying Modified Versions.
-
-  If you modify a copy of the Library, and, in your modifications, a
-facility refers to a function or data to be supplied by an Application
-that uses the facility (other than as an argument passed when the
-facility is invoked), then you may convey a copy of the modified
-version:
-
-   a) under this License, provided that you make a good faith effort to
-   ensure that, in the event an Application does not supply the
-   function or data, the facility still operates, and performs
-   whatever part of its purpose remains meaningful, or
-
-   b) under the GNU GPL, with none of the additional permissions of
-   this License applicable to that copy.
-
-  3. Object Code Incorporating Material from Library Header Files.
-
-  The object code form of an Application may incorporate material from
-a header file that is part of the Library.  You may convey such object
-code under terms of your choice, provided that, if the incorporated
-material is not limited to numerical parameters, data structure
-layouts and accessors, or small macros, inline functions and templates
-(ten or fewer lines in length), you do both of the following:
-
-   a) Give prominent notice with each copy of the object code that the
-   Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the object code with a copy of the GNU GPL and this license
-   document.
-
-  4. Combined Works.
-
-  You may convey a Combined Work under terms of your choice that,
-taken together, effectively do not restrict modification of the
-portions of the Library contained in the Combined Work and reverse
-engineering for debugging such modifications, if you also do each of
-the following:
-
-   a) Give prominent notice with each copy of the Combined Work that
-   the Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the Combined Work with a copy of the GNU GPL and this license
-   document.
-
-   c) For a Combined Work that displays copyright notices during
-   execution, include the copyright notice for the Library among
-   these notices, as well as a reference directing the user to the
-   copies of the GNU GPL and this license document.
-
-   d) Do one of the following:
-
-       0) Convey the Minimal Corresponding Source under the terms of this
-       License, and the Corresponding Application Code in a form
-       suitable for, and under terms that permit, the user to
-       recombine or relink the Application with a modified version of
-       the Linked Version to produce a modified Combined Work, in the
-       manner specified by section 6 of the GNU GPL for conveying
-       Corresponding Source.
-
-       1) Use a suitable shared library mechanism for linking with the
-       Library.  A suitable mechanism is one that (a) uses at run time
-       a copy of the Library already present on the user's computer
-       system, and (b) will operate properly with a modified version
-       of the Library that is interface-compatible with the Linked
-       Version.
-
-   e) Provide Installation Information, but only if you would otherwise
-   be required to provide such information under section 6 of the
-   GNU GPL, and only to the extent that such information is
-   necessary to install and execute a modified version of the
-   Combined Work produced by recombining or relinking the
-   Application with a modified version of the Linked Version. (If
-   you use option 4d0, the Installation Information must accompany
-   the Minimal Corresponding Source and Corresponding Application
-   Code. If you use option 4d1, you must provide the Installation
-   Information in the manner specified by section 6 of the GNU GPL
-   for conveying Corresponding Source.)
-
-  5. Combined Libraries.
-
-  You may place library facilities that are a work based on the
-Library side by side in a single library together with other library
-facilities that are not Applications and are not covered by this
-License, and convey such a combined library under terms of your
-choice, if you do both of the following:
-
-   a) Accompany the combined library with a copy of the same work based
-   on the Library, uncombined with any other library facilities,
-   conveyed under the terms of this License.
-
-   b) Give prominent notice with the combined library that part of it
-   is a work based on the Library, and explaining where to find the
-   accompanying uncombined form of the same work.
-
-  6. Revised Versions of the GNU Lesser General Public License.
-
-  The Free Software Foundation may publish revised and/or new versions
-of the GNU Lesser General Public License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.
-
-  Each version is given a distinguishing version number. If the
-Library as you received it specifies that a certain numbered version
-of the GNU Lesser General Public License "or any later version"
-applies to it, you have the option of following the terms and
-conditions either of that published version or of any later version
-published by the Free Software Foundation. If the Library as you
-received it does not specify a version number of the GNU Lesser
-General Public License, you may choose any version of the GNU Lesser
-General Public License ever published by the Free Software Foundation.
-
-  If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.

-# ansiterm
-    import "github.com/juju/ansiterm"
-
-Package ansiterm provides a Writer that writes out the ANSI escape
-codes for color and styles.
-
-
-
-
-
-
-
-## type Color
-``` go
-type Color int
-```
-Color represents one of the standard 16 ANSI colors.
-
-
-
-``` go
-const (
-    Default Color
-    Black
-    Red
-    Green
-    Yellow
-    Blue
-    Magenta
-    Cyan
-    Gray
-    DarkGray
-    BrightRed
-    BrightGreen
-    BrightYellow
-    BrightBlue
-    BrightMagenta
-    BrightCyan
-    White
-)
-```
-
-
-
-
-
-
-
-
-### func (Color) String
-``` go
-func (c Color) String() string
-```
-String returns the name of the color.
-
-
-
-## type Context
-``` go
-type Context struct {
-    Foreground Color
-    Background Color
-    Styles     []Style
-}
-```
-Context provides a way to specify both foreground and background colors
-along with other styles and write text to a Writer with those colors and
-styles.
-
-
-
-
-
-
-
-
-
-### func Background
-``` go
-func Background(color Color) *Context
-```
-Background is a convenience function that creates a Context with the
-specified color as the background color.
-
-
-### func Foreground
-``` go
-func Foreground(color Color) *Context
-```
-Foreground is a convenience function that creates a Context with the
-specified color as the foreground color.
-
-
-### func Styles
-``` go
-func Styles(styles ...Style) *Context
-```
-Styles is a convenience function that creates a Context with the
-specified styles set.
-
-
-
-
-### func (\*Context) Fprint
-``` go
-func (c *Context) Fprint(w sgrWriter, args ...interface{})
-```
-Fprint will set the sgr values of the writer to the specified foreground,
-background and styles, then formats using the default formats for its
-operands and writes to w. Spaces are added between operands when neither is
-a string. It returns the number of bytes written and any write error
-encountered.
-
-
-
-### func (\*Context) Fprintf
-``` go
-func (c *Context) Fprintf(w sgrWriter, format string, args ...interface{})
-```
-Fprintf will set the sgr values of the writer to the specified
-foreground, background and styles, then write the formatted string,
-then reset the writer.
-
-
-
-### func (\*Context) SetBackground
-``` go
-func (c *Context) SetBackground(color Color) *Context
-```
-SetBackground sets the background to the specified color.
-
-
-
-### func (\*Context) SetForeground
-``` go
-func (c *Context) SetForeground(color Color) *Context
-```
-SetForeground sets the foreground to the specified color.
-
-
-
-### func (\*Context) SetStyle
-``` go
-func (c *Context) SetStyle(styles ...Style) *Context
-```
-SetStyle replaces the styles with the new values.
-
-
-
-## type Style
-``` go
-type Style int
-```
-
-
-``` go
-const (
-    Bold Style
-    Faint
-    Italic
-    Underline
-    Blink
-    Reverse
-    Strikethrough
-    Conceal
-)
-```
-
-
-
-
-
-
-
-
-### func (Style) String
-``` go
-func (s Style) String() string
-```
-
-
-## type TabWriter
-``` go
-type TabWriter struct {
-    Writer
-    // contains filtered or unexported fields
-}
-```
-TabWriter is a filter that inserts padding around tab-delimited
-columns in its input to align them in the output.
-
-It also setting of colors and styles over and above the standard
-tabwriter package.
-
-
-
-
-
-
-
-
-
-### func NewTabWriter
-``` go
-func NewTabWriter(output io.Writer, minwidth, tabwidth, padding int, padchar byte, flags uint) *TabWriter
-```
-NewTabWriter returns a writer that is able to set colors and styels.
-The ansi escape codes are stripped for width calculations.
-
-
-
-
-### func (\*TabWriter) Flush
-``` go
-func (t *TabWriter) Flush() error
-```
-Flush should be called after the last call to Write to ensure
-that any data buffered in the Writer is written to output. Any
-incomplete escape sequence at the end is considered
-complete for formatting purposes.
-
-
-
-### func (\*TabWriter) Init
-``` go
-func (t *TabWriter) Init(output io.Writer, minwidth, tabwidth, padding int, padchar byte, flags uint) *TabWriter
-```
-A Writer must be initialized with a call to Init. The first parameter (output)
-specifies the filter output. The remaining parameters control the formatting:
-
-
-	minwidth	minimal cell width including any padding
-	tabwidth	width of tab characters (equivalent number of spaces)
-	padding		padding added to a cell before computing its width
-	padchar		ASCII char used for padding
-			if padchar == '\t', the Writer will assume that the
-			width of a '\t' in the formatted output is tabwidth,
-			and cells are left-aligned independent of align_left
-			(for correct-looking results, tabwidth must correspond
-			to the tab width in the viewer displaying the result)
-	flags		formatting control
-
-
-
-## type Writer
-``` go
-type Writer struct {
-    io.Writer
-    // contains filtered or unexported fields
-}
-```
-Writer allows colors and styles to be specified. If the io.Writer
-is not a terminal capable of color, all attempts to set colors or
-styles are no-ops.
-
-
-
-
-
-
-
-
-
-### func NewWriter
-``` go
-func NewWriter(w io.Writer) *Writer
-```
-NewWriter returns a Writer that allows the caller to specify colors and
-styles. If the io.Writer is not a terminal capable of color, all attempts
-to set colors or styles are no-ops.
-
-
-
-
-### func (\*Writer) ClearStyle
-``` go
-func (w *Writer) ClearStyle(s Style)
-```
-ClearStyle clears the text style.
-
-
-
-### func (\*Writer) Reset
-``` go
-func (w *Writer) Reset()
-```
-Reset returns the default foreground and background colors with no styles.
-
-
-
-### func (\*Writer) SetBackground
-``` go
-func (w *Writer) SetBackground(c Color)
-```
-SetBackground sets the background color.
-
-
-
-### func (\*Writer) SetForeground
-``` go
-func (w *Writer) SetForeground(c Color)
-```
-SetForeground sets the foreground color.
-
-
-
-### func (\*Writer) SetStyle
-``` go
-func (w *Writer) SetStyle(s Style)

-// Filter implementation
-
-// A cell represents a segment of text terminated by tabs or line breaks.

-// segment's size in bytes, its width in runes, and whether it's an htab
-// ('\t') terminated cell.

-}
-
-// A Writer is a filter that inserts padding around tab-delimited
-// columns in its input to align them in the output.
-//
-// The Writer treats incoming bytes as UTF-8 encoded text consisting
-// of cells terminated by (horizontal or vertical) tabs or line
-// breaks (newline or formfeed characters). Cells in adjacent lines
-// constitute a column. The Writer inserts padding as needed to
-// make all cells in a column have the same width, effectively
-// aligning the columns. It assumes that all characters have the
-// same width except for tabs for which a tabwidth must be specified.
-// Note that cells are tab-terminated, not tab-separated: trailing
-// non-tab text at the end of a line does not form a column cell.
-//
-// The Writer assumes that all Unicode code points have the same width;
-// this may not be true in some fonts.
-//
-// If DiscardEmptyColumns is set, empty columns that are terminated
-// entirely by vertical (or "soft") tabs are discarded. Columns
-// terminated by horizontal (or "hard") tabs are not affected by
-// this flag.
-//
-// If a Writer is configured to filter HTML, HTML tags and entities
-// are passed through. The widths of tags and entities are
-// assumed to be zero (tags) and one (entities) for formatting purposes.
-//
-// A segment of text may be escaped by bracketing it with Escape
-// characters. The tabwriter passes escaped text segments through
-// unchanged. In particular, it does not interpret any tabs or line
-// breaks within the segment. If the StripEscape flag is set, the
-// Escape characters are stripped from the output; otherwise they
-// are passed through as well. For the purpose of formatting, the
-// width of the escaped text is always computed excluding the Escape
-// characters.
-//
-// The formfeed character ('\f') acts like a newline but it also
-// terminates all columns in the current line (effectively calling
-// Flush). Cells in the next line start new columns. Unless found
-// inside an HTML tag or inside an escaped text segment, formfeed
-// characters appear as newlines in the output.
-//
-// The Writer must buffer input internally, because proper spacing
-// of one line may depend on the cells in future lines. Clients must
-// call Flush when done calling Write.
