=========================================================================
== PURPOSE ==
This package, initially a collection of Michael Covington's private macros, provides
numerous minor LaTeX enhancements for linguistics, including multiple diacritics on
the same letter, interlinear glosses (word-by-word translations), Discourse
Representation Structures, and example numbering.
== CONTENTS ==
The package consists of the following files:
* covington.sty: the actual package
* covington.tex: the documentation
* README (this file)
== CHANGES ==
* Version 2.16 (2025年12月30日)
	- Add subnumberrefsep option to subexamples environment.
	- Fix reference to subexample that is nested in an enumeration.
* Version 2.15 (2025年08月13日)
	- Fix definition of covexercise if no chapters exist.
	- Enhance reflist documentation.
* Version 2.14 (2023年12月11日)
	- Add \ownexcounterprep macro to add a prefix (e.g., the chapter)
	 to the (owncounter) example counter.
	- Document how to (not) number examples per chapter.
* Version 2.13 (2023年12月02日)
	- Fix example numbering with chapters (#16).
* Version 2.12 (2023年06月25日)
	- Fix issue with redefinitions of \glosslineone/\glosslinetwo/\glosslinethree,
	 which could get lost along the text (#13).
* Version 2.11 (2023年06月17日)
	- Add support for judgment markers in examples and glosses.
	- Add support for customization of spacing between gloss lines.
	- Add support for gloss comment lines via optional arguments.
	- Add support for translation lines on the right side of glosses (via new tlr* option).
* Version 2.10 (2023年06月02日)
	- Use LaTeX's own keyval mechanism rather than xkeyval.
	- Introduce a better interface to customize the appearance of examples. Now everything can
	 be easily adjusted globally and locally via key-val options. This entails the following changes:
	 * Allow to globally set example options via the new macro \setexampleoptions.
	 * Add way to customize example and subexample number format.
	 * Add new example options: fs, fsno, fspreamble, fspostamble, leftmargin, addnumbersep,
	 addsubnumbersep, numberformat, subnumberformat, and fnnumberformat.
	- Add new gloss options: fspreamble, fspostamble, fstl, and enquotetl.
	 This allows for full customization of glosses via options, both locally and globally.
	- Package options now all have a key-value format as well.
	- Introduce new package choice-option fnexamplecounter that supersedes the two boolean,
	 mutually exclusive options ownfncounter and ownfncounter* (which are still supported
	 for backwards compatibility reasons).
	- Major documentation revisions.
* Version 2.9 (2023年05月26日):
	- Add postamble and postamble* options to example and subexamples environment.
	- Add \expreamble, \subexpreamble, \expostamble and \subexpostamble macros.
	- Some documentation fixes.
* Version 2.8 (2022年08月30日):
 - Add ownfncounter and ownfncounter* options to allow for separate counting
 of examples in footnotes. The starred option resets the counter at each footnote.
 - Add preamble option to example environment.
* Version 2.7 (2021年09月01日):
 - Add postamble gloss macro option for arbitrary text that is appended to the free
 translation line (after closing quotation marks).
 - Add glosslinepostamble command to markup this text.
* Version 2.6 (2021年05月19日):
 - New length \exampleind to adjust (increase/decrease) the indentation (left margin)
 of examples.
* Version 2.5 (2021年03月21日):
	- Fix metrics of stacked diacritics with XeTeX/LuaTeX.
* Version 2.4 (2020年01月02日):
	- Fix definition of covexercise if no subsection counter exists.
* Version 2.3 (2019年06月21日):
	- Add preamble option to subexamples environment.
	- Allow to use covington together with the drs package.
	- Documentation fixes and restructuring.
* Version 2.2 (2019年06月04日):
	- Add new option owncounter that makes covington use an own counter for examples
	 (rather than the equation counter).
	- Add starred \exampleno* command that outputs the current example number value
	 without stepping it.
	- Add macros \covexamplefs and \covexamplenofs for global setting of example text
	 markup.
* Version 2.1 (2019年05月12日):
	- Add new option noglossbreaks that tries to prevent page breaks within glosses.
	- Add \glosspreamble command and preamble gloss macro option for arbitrary text
	 preceding glosses.
* Version 2.0 (2018年12月10日):
	- Add new gloss macros (\digloss and \trigloss) for a more convenient,
	 flexible and robust gloss insertion.
	- Add \glot command for customizable gloss translation line,
	 together with customization possibilities.
	- Add possibility to customize \sentence font setting.
	- Add \lexp, \lcon and \lmean markup macros.
* Version 1.8 (2018年12月07日):
	- Fix font markup of second gloss line (do not force rm).
	- Add possibility to customize gloss line font setting.
	- Add possibility to customize example number display.
* Version 1.7 (2018年09月08日):
	- Fix alignment in subexamples.
	- Improve manual.
* Version 1.6 (2018年09月07日):
	- Introduce new environment subexamples for sub-examples such as 1a.
	- Introduce new command \pxref that outputs references to examples including
 parentheses.
* Version 1.5 (2018年08月24日):
	- Introduce new option "keeplayout" that allows to opt-out the
	 layout presettings covington does (\raggedbottom, \textfloatsep).
* Version 1.4 (2017年05月23日):
	- Introduce a new macro \twodias that supersedes the rather odd \twoacc
	 (which is kept for backwards compatibility).
	- Introduce macro \SetDiaOffset for more convenient setting of vertical
	 distance in stacked diacritics.
	- LaTeX 2.09 is no longer officially supported (it might continue to work,
	 but is not tested).
	- Documentation file converted to un*x line endings.
* Version 1.3 (2017年04月05日):
 - Gloss variants \xgll and \xglll that work inside macros (such as footnotes)
 but require explicit gloss line end markers (\xgle).
	- Provide way to globally alter indentation and vertical distance of reflists
 (new lengths \reflistindent, \reflistparsep and \reflistitemsep).
* Version 1.2 (2016年08月26日):
	- New length \examplenumbersep to adjust (increase) the horizontal space
	 between example number and example text.
	
	- Add some more info about bibliography generation.
* Version 1.1a (2016年07月07日):
	- Fix encoding problem in documentation and some typos. No change in functionality.
* Version 1.1 (2016年07月06日):
	- The package now uses NFSS font commands if available (fallback for LaTeX 2.09
	 is still provided).
	- Work around clash with classes/packages that define their own example and
	 examples environments (most notably the beamer class) as well as execise
	 environments. The covington package no longer blindly attempts to define
	 these environments. By default, it does not define them if they are already
	 defined (covington's own environments, however, are still available via aliases).
	 By means of a new package option, a redefinition can also be forced.
	- New length \twoaccsep allows for the adjustment of the distance between stacked
	 accents.
	- Update manual.
	- New maintainer: J. Spitzmueller.
	- License has been changed to LPPL (in agreement with M. Covington).
	- Introduce version numbers. Arbitrarily, we start with 1.1.
