| 15 | * This script converts a DocBook document into a set of HTML files,
|
|---|
| 16 | * a HHP descriptor and a HHC table of contents.
|
|---|
| 17 | * The files must be further processed on MS-Windows using the HTML Help Workshop
|
|---|
| 18 | * application (HHC.EXE) in order to get the required final CHM file.
|
|---|
| 19 | *
|
|---|
| 20 | * If HHP generation fails because of non-ASCII characters, try to modify the following
|
|---|
| 21 | * output parameters:
|
|---|
| 22 | * <xsl:param name="htmlhelp.encoding" select="'windows-1250'"/>
|
|---|
| 23 | * <xsl:param name="chunker.output.encoding" select="'windows-1250'"/>
|
|---|
| 24 | * <xsl:param name="saxon.character.representation" select="'native'"/>
