A service to support the substitution and resubstitution of path variables.
A path variable must be specified with the following synatx: "$("<variable-name>")".
Path variables are not case sensitive and are always provided as a UCB-complient URL's
(for example: "file:///c:/temp" or "file:///usr/install"). This is mandatory to support an
optional remote file system.
A user defined list of path variables is supported. This list is stored in the Office
configuration file (org/openoffice/Office/Substitution.xml). Please have a look at the
schema definition file which configuration structure this file uses.
There is also a set of variables that have pre-defined values:
$(inst)
Installation path of the Office Basis layer.
$(prog)
Program path of the Office Basis layer.
$(brandbaseurl)
Installation path of the the Office Brand layer.
$(user)
The user installation directory.
$(work)
The work directory of the user. Under Windows this would be the
"MyDocuments" subdirectory. Under Unix this would be the home-directory
$(home)
The home directory of the user. Under Unix this would be the home-
directory. Under Windows this would be the "Documents and Settings\"
subdirectory.
$(temp)
The current temporary directory.
$(path)
The value of PATH environment variable.
$(lang)
The country code used by the Office, like 01=english, 49=german.
$(langid)
The language code used by the Office, like 0x0009=english, 0x0409=english us.
$(vlang)
The language used by the Office as a string. Like "german" for a german Office.
Attention: Most predefined variables describe an absolute path.
The only exceptions are: $(lang), $(langid) and $(vlang).
Therefore the service implementation should only substitute variables which
are located at the start of a provided path string or are part of a multi-path.
This special service is not designed to be a text substiution but shall
provide (a) valid substituted path(s).
