+ If you put it in a file
+\begin_inset Flex CharStyle:Code
+status collapsed
+
+\begin_layout Plain Layout
+myarticle.layout
+\end_layout

+, the header of this file should be:

+\end_layout
+
+\begin_layout LyX-Code
+
+\size small
+#
+\backslash
+DeclareLaTeXClass[article]{article (with my own headings)}
+\end_layout
+
+\begin_layout Standard
+This declares a text class
+\begin_inset Flex CharStyle:Code
+status collapsed
+
+\begin_layout Plain Layout
+myarticle
+\end_layout
+
+\end_inset
+
+, associated with the LaTeX document class
+\begin_inset Flex CharStyle:Code
+status collapsed
+
+\begin_layout Plain Layout
+article.cls
+\end_layout
+
+\end_inset
+
+ and described as
+\begin_inset Quotes eld
+\end_inset
+
+article (with my own headings)
+\begin_inset Quotes erd
+\end_inset
+
+.
+ If your text class depends on several packages, you can declare it as:
+\end_layout
+
+\begin_layout LyX-Code
+
+\size small
+#% Do not delete the line below; configure depends on this
+\end_layout
+
+\begin_layout LyX-Code
+
+\size small
+#
+\backslash
+DeclareLaTeXClass[article,foo.sty]{article (with my own headings)}
+\end_layout
+
+\begin_layout Standard
+This indicates that your text class uses the
+\begin_inset Flex CharStyle:Code
+status collapsed
+
+\begin_layout Plain Layout
+foo.sty
+\end_layout
+
+\end_inset
+
+ package.
+ Finally, it is also possible to declare classes for DocBook code.
+ Typical declarations will look like:
+\end_layout
+
+\begin_layout LyX-Code
+
+\size small
+#% Do not delete the line below; configure depends on this
+\end_layout
+
+\begin_layout LyX-Code
+
+\size small
+#
+\backslash
+DeclareDocBookClass[article]{SGML (DocBook article)}
+\end_layout
+
+\begin_layout Standard
+Note that these declarations can also be given an optional parameter declaring
+ the name of the document class (but not a list).
+\end_layout
+
+\begin_layout Standard
+So, to be as explicit as possible, the form of the layout declaration is:
+\end_layout
+
+\begin_layout LyX-Code
+
+\size small
+#
+\backslash
+DeclareLaTeXClass[class,package.sty]{layout description}
+\end_layout
+
+\begin_layout Standard
+The class need only be specified if the name of the LaTeX class file and
+ the name of the layout file are different; if the name of the class file
+ is not specified, then LyX will simply assume that it is the same as the
+ name of the layout file.
+\end_layout
+
+\begin_layout Standard
+When the text class has been modified to your taste, all you have to do
+ is to copy it either to
+\begin_inset Flex CharStyle:Code
+status collapsed
+
+\begin_layout Plain Layout
+LyXDir/layouts/
+\end_layout
+
+\end_inset
+
+ or to
+\begin_inset Flex CharStyle:Code
+status collapsed
+
+\begin_layout Plain Layout
+UserDir/layouts

+\begin_inset Flex CharStyle:MenuItem
+status collapsed
+
+\begin_layout Plain Layout
+Tools\SpecialChar \menuseparator
+Reconfigure
+\end_layout
+
+\end_inset
+
+, exit LyX and restart.
+ Then your new text class should be available along with the others.
+\end_layout
+
+\begin_layout Standard
+Once the layout file is installed, you can edit it and see your changes
+ without having to reconfigure or to restart LyX.
+
+\begin_inset Foot
+status collapsed
+
+\begin_layout Plain Layout
+In versions of LyX prior to 1.6, this was not true.
+ As a result, editing layout files was very time consuming, since you had
+ constantly to restart LyX to see changes.
+\end_layout
+
+\end_inset
+
+ You can force a reload of the current layout by using the LyX function
+
+\begin_inset Flex CharStyle:MenuItem
+status collapsed
+
+\begin_layout Plain Layout
+layout-reload
+\end_layout
+
+\end_inset
+
+.
+ There is no default binding for this function—though, of course, you can
+ bind it to a key yourself.
+ But you will normally use this function simply by entering it in the mini-buffe
+r.

+ It is

+ In fact, it is

+ Use a test document.
+ Syntax errors and the like in your layout file could cause peculiar behavior.
+ In particular, such errors could cause LyX to regard the current layout
+ as invalid and to attempt to switch to some other layout.
+\begin_inset Foot

+
+\begin_layout Plain Layout
+Really bad syntax errors may even caused LyX to exit.
+ This is because certain sorts of errors may make LyX unable to read

+\begin_layout Subsection
+The Module Declaration
+\end_layout
+
+\begin_layout Standard
+A module must begin with a line like the following:
+\end_layout
+
+\begin_layout LyX-Code
+#
+\backslash
+DeclareLyXModule[endnotes.sty]{Endnotes}
+\end_layout
+
+\begin_layout Standard
+The mandatory argument, in curly brackets, is the name of the module, as
+ it should appear in
+\begin_inset Flex CharStyle:MenuItem
+status collapsed
+
+\begin_layout Plain Layout
+Document\SpecialChar \menuseparator
+Settings
+\end_layout
+
+\end_inset
+
+.
+ The argument in square brackets is optional: It declares any LaTeX packages
+ on which the module depends.
+ Please note that only packages about which LyX knows should be listed in
+ the square brackets.
+\begin_inset Foot
+status collapsed
+
+\begin_layout Plain Layout
+The list of such packages is documented only in the source code.
+\end_layout
+
+\end_inset
+
+ LyX will not check for arbitrary packages.
+ It is also possible to use the form
+\begin_inset Flex CharStyle:MenuItem
+status collapsed
+
+\begin_layout Plain Layout
+from->to
+\end_layout
+
+\end_inset
+
+ as an optional argument, which declares that the module can only be used
+ when there exists a conversion chain between the formats `
+\begin_inset Flex CharStyle:Code
+status collapsed
+
+\begin_layout Plain Layout
+from
+\end_layout
+
+\end_inset
+
+' and `
+\begin_inset Flex CharStyle:Code
+status collapsed
+
+\begin_layout Plain Layout
+to
+\end_layout
+
+\end_inset
+
+'.
+\end_layout
+
+\begin_layout Standard
+The module declaration should then be followed by lines like the following:
+\end_layout
+
+\begin_layout LyX-Code
+#DescriptionBegin
+\end_layout
+
+\begin_layout LyX-Code
+#Adds an endnote command, in addition to footnotes.
+
+\end_layout

+\begin_layout LyX-Code
+#You will need to add

+\end_layout

+\end_layout

+\begin_inset Flex CharStyle:MenuItem

+\begin_layout Plain Layout

+ The
+\begin_inset Flex CharStyle:Code
+status collapsed
+
+\begin_layout Plain Layout
+Requires

+ the
+\begin_inset Flex CharStyle:Code
+status collapsed
+
+\begin_layout Plain Layout
+Excludes
+\end_layout
+
+\end_inset
+
+ line is used to identify modules with which this one may not be used.
+ Both are optional, and, as shown, multiple modules should be separated
+ with the pipe symbol: |.
+ Note that the required modules are treated disjunctively:
+\emph on
+at least one
+\emph default
+ of the required modules must be used.
+ Similarly,
+\emph on

+ So
+\begin_inset Flex CharStyle:Code

+\end_layout
+
+\begin_layout Standard
+This tag was introduced with LyX 1.4.0.
+ Layout files from LyX 1.3.x and earlier don't have an explicit file format
+ and are considered to be of format 1.
+ The format for the present version of LyX is format 20.
+ But each version of LyX is capable of reading earlier versions' layout
+ files, just as they are capable of reading files produced by earlier versions
+ of LyX.
+ There is, however, no provision for converting to earlier formats.
+ So LyX 1.6.x will not read layout files in format 20 but only files in format
+ 11 or earlier.
