# install.sh - Set up user environment for a XML/XSLT distribution

# This is as an interactive installer for updating your
# environment to use an XML/XSLT distribution such as the DocBook
# XSL Stylesheets. Its main purpose is to configure your
# environment with XML catalog data and schema "locating rules"
# data provided in the XML/XSLT distribution.
#
# Although this installer was created for the DocBook project, it
# is a general-purpose tool that can be used with any XML/XSLT
# distribution that provides XML/SGML catalogs and locating rules.
#
# This script is mainly intended to make things easier for you if
# you want to install a particular XML/XSLT distribution that has
# not (yet) been packaged for your OS distro (Debian, Fedora,
# whatever), or to use "snapshot" or development releases 
#
# It works by updating your shell startup file (e.g., .bashrc and
# .cshrc) and .emacs file and by finding or creating a writable
# CatalogManager.properties file to update.
#
# It makes backup copies of any files it touches, and also
# generates a uninstall.sh script for reverting its changes.
#
# In the same directory where it is located, it expects to find
# the following four files:
#   - locatingrules.xml
#   - catalog.xml
#   - catalog
#   - .urilist
# And if it's unable to locate a CatalogManager.properties file in
# your environment, it expects to find an "example" one in the
# same directory as itself, which it copies over to your
# ~/.resolver directory.
#
# If the distribution contains any executables, change the value
# of the thisBinDir to a colon-separated list of the pathnames of
# the directories that contain those executables.

# mydir is the "canonical" absolute pathname for install.sh
mydir=$(cd -P $(dirname $0) && pwd -P) || exit 1

thisLocatingRules=$mydir/locatingrules.xml
thisXmlCatalog=$mydir/catalog.xml

# URIs to test for catalog resolution
thisUriList=$mydir/.urilist
exampleCatalogManager=$mydir/.CatalogManager.properties.example
thisCatalogManager=$HOME/.resolver/CatalogManager.properties

# thisBinDir directory is a colon-separated list of the pathnames
# to all directories that contain executables provided with the
# distribution (for example, the DocBook XSL Stylesheets
# distribution contains a "docbook-xsl-update" convenience script
# for rsync'ing up to the latest docbook-xsl snapshot). The
# install.sh script adds the value of thisBinDir to your PATH
# environment variable
