# Shell script File to start a Calibre configuration on Linux
# giving explicit control of the location of:
# - Calibre Program Files
# - Calibre Library Files
# - Calibre Config Files
# - Calibre Metadata database
# - Calibre Source files
# - Calibre Temp Files
# By setting the paths correctly it can be used to run:
# - A "portable calibre" off a USB stick.
# - A network installation with local metadata database
# (for performance) and books stored on a network share
# - A local installation using customised settings
#
# If trying to run off a USB stick then the folder structure
# shown below is recommended (relative to the location of
# this script file). This structure can also be used when
# running of a local hard disk if you want to get the level
# of control this script file provides.
# - Calibre Location of linux program files
# - CalibreConfig Location of Configuration files
# - CalibreLibrary Location of Books and metadata
# - CalibreSource Location of Calibre Source files (Optional)
#
# This script file is designed so that if you create the recommended
# folder structure then it can be used 'as is' without modification.
# To use your own structure, simply set the variables in the generated configuration file.
#
# More information on the Environment Variables used by Calibre can
# be found at:
# https://manual.calibre-ebook.com/customize.html#environment-variables
#
# NOTE: It is quite possible to have both Windows and Linux binaries on the same
# USB stick but set up to use the same calibre settings otherwise.
# In this case you use:
# - calibre-portable.bat to run the Windows version
# - calibre-portable.sh to run the Linux version
#
# CHANGE HISTORY
# ¬¬¬¬¬¬¬¬¬¬¬¬¬¬
# 22 Jan 2012 itimpi ----- First version based on the calibre-portable.bat file for Windows
# It should have identical functionality but for a linux environment.
# It might work on MacOS but that has not been validated.
#
# 02 Feb 2015 eschwartz -- Fix path issues, allow setting each location in one variable, allow
# specifying a list of libraries in descending order of priority.
#
# 01 Apr 2015 eschwartz -- Fix temp dir and permissions, migrate settings to configuration file.
# -----------------------------------------------------
# On exit, make sure all files are marked world-writable.
# This allows you to use calibre on other computers
# without changing fstab rules and suchlike.
# You can now use an ext3 drive instead of vfat so the
# binaries and script will be executable.

#
# -- Location where the metadata.db file is located. If not set
# -- then the same location as the library folder will be assumed.
# -- This option is typically used to get better performance when the
# -- library is on a (slow) network drive. Putting the metadata.db
# -- file locally then makes gives a big performance improvement.
#
# -- NOTE. If you use this option, then the ability to switch
# -- libraries within calibre will be disabled. Therefore
# -- you do not want to set it if the metadata.db file
# -- is at the same location as the book files.
#
# -- Another point to watch is that plugins can cause problems

# -- can specifically use the search path by leaving the BIN_DIR blank.
#
# -- This folder can be populated by copying the /opt/calibre folder
