	TODO: Change the following local-only config before any public release.
	The log file should be: $GTD_IN/logs/urls/urls.YYYY.txt
	Or just: $GTD_IN/logs/urls.txt

	TODO: The edit_log() function is currently incomplete. It will only launch
	an editor from the shell and only if that editor is a GUI editor (in this
	case, MacVim). If I release this script publicly, I will still need to
	implement funtionality to launch a GUI editor normally (with the 'open'
	AppleScript commmand) as well as a command-line editor run in the Terminal.

---------- USER CONFIGURATION ----------------------------------------
-- Default log directory to use if one is not read from config file:
--set log_dir to POSIX path of (path to application support folder from user domain) & "Jazzhead/Log Page/"
set log_dir to POSIX path of (path to desktop folder) & "Log Page/" -- :DEBUG:

-- Log file name:
set log_name to "urls.txt"

-- Default categories/labels if none are found in (or there is no)
-- URL file. Modify as desired:
set default_cats to "Development
Development:AppleScript
Development:AppleScript:Mail
Design
Productivity:GTD
Apple:Mac OS X
Apple:iOS
Career
Education
Health
Health:Diet
Health:Fitness
General"

-- Text editor to use if manually editing the log file.
--
-- This example:
--	1. Opens the file using MacVim ('mvim' as installed by MacPorts)
--	2. Switches the local working directory for just that buffer to the
--	    directory containing the file ('lcd')
--	3. Gives the MacVim window a name ('--servername').
--
set text_editor to "/opt/local/bin/mvim \"+lcd %:p:h\" --servername LOG_PAGE"

-- Should the specified editor be launched from the unix shell?
set should_use_shell to true
---------- END User Configuration ----------------------------------------

---------- ADVANCED (EXPERIMENTAL) ---------------------------------------------
-- For advanced users familiar with the command-line, override the default log
-- directory path. This probably won't be in a public release.
--
-- Grab an exported shell environment variable from a config file to use as the
-- log directory path. For this example, I have a "~/.gtdrc" config file that I
-- source from my "~/.bash_profile" file so that it exportss environment
-- variables relating to my GTD system. That makes those variables available to
-- any of the shell scripts and tools that I use. For instance, when I'm
-- editing files in Vim, I can write paths to other files using one of the
-- environment variables rather than a full or relative path and the 'gf'
-- command will work for jumping to that file. The config file looks like this:
--
--         # ~/.gtdrc
--         #
--         # File locations for GTD documents
--         #
--         export GTD_DIR=$HOME/Documents/org  # GTD root directory
--         export GTD_IN=$GTD_DIR/content      # source/input files
--         export GTD_OUT=$GTD_DIR/html        # generated HTML output files
--         export GTD_LIB=$GTD_DIR/lib         # code library files
--         export GTD_BIN=$GTD_LIB/script      # scripts
--
-- Remove (or comment out) the "(*" and "*)" comment markers below to use this
-- section. Make sure you also configure the two variables for your system.
--(*
--------------- USER CONFIGURATION ----------
-- Path to your config file:
set cfg_file to POSIX path of (path to home folder) & ".gtdrc"
-- The environment variable you're interested in:
set env_var to "GTD_IN"
--------------- END User Configuration ---------

-- Check for environment variable in config file:
set s to "egrep '\\<" & env_var & "=' " & quoted form of cfg_file &
	" > /dev/null 2>&1; echo $?"
set shell_status to (do shell script s) as integer
-- Source the config file and echo the desired variable:
if shell_status is 0 then -- (means that grep found a match)
	set s to ". " & quoted form of cfg_file & " && echo $" & env_var
	set gtd_in_dir to do shell script s
	set log_dir to gtd_in_dir & "/logs/"

	--------------------
	-- OPTIONAL: Override the Text editor to integrate with my GTD system.
	--
	-- This example:
	--	1. Opens the file using MacVim ('mvim' as installed by MacPorts)
	--	2. Switches the local working directory ('lcd') for just that buffer to
	--	    my GTD content directory ($GTD_IN after escaping potential spaces)
	--	3. Gives the MacVim window a name ('--servername').

	----- First, escape any potential spaces in the directory path:
	--
	--set gtd_in_dir to gtd_in_dir & " foo    bar" -- :DEBUG: spaces in path
	--
	set s to "echo " & quoted form of gtd_in_dir & " | sed 's/ \\{1,\\}/\\\\ /g'" -- escape spaces
	set gtd_in_dir to do shell script s
	--
	--log gtd_in_dir -- :DEBUG: need to use 'log' to see the value w/o AppleScript escapes

	----- Finally, set the editor with all of the options:
	--
	set text_editor to "/opt/local/bin/mvim \"+lcd " & gtd_in_dir & "\" --servername GTD --remote-silent"
	--
	--log text_editor -- :DEBUG:

	TODO: Change the following local-only config before any public release.
	The log file should be: $GTD_IN/logs/urls/urls.YYYY.txt
	Or just: $GTD_IN/logs/urls.txt

	TODO: The edit_log() function is currently incomplete. It will only launch
	an editor from the shell and only if that editor is a GUI editor (in this
	case, MacVim). If I release this script publicly, I will still need to
	implement funtionality to launch a GUI editor normally (with the 'open'
	AppleScript commmand) as well as a command-line editor run in the Terminal.

---------- USER CONFIGURATION ----------------------------------------
-- Default log directory to use if one is not read from config file:
--set log_dir to POSIX path of (path to application support folder from user domain) & "Jazzhead/Log Page/"
set log_dir to POSIX path of (path to desktop folder) & "Log Page/" -- :DEBUG:

-- Log file name:
set log_name to "urls.txt"

-- Default categories/labels if none are found in (or there is no)
-- URL file. Modify as desired:
set default_cats to "Development
Development:AppleScript
Development:AppleScript:Mail
Design
Productivity:GTD
Apple:Mac OS X
Apple:iOS
Career
Education
Health
Health:Diet
Health:Fitness
General"

-- Text editor to use if manually editing the log file.
--
-- This example:
--	1. Opens the file using MacVim ('mvim' as installed by MacPorts)
--	2. Switches the local working directory for just that buffer to the
--	    directory containing the file ('lcd')
--	3. Gives the MacVim window a name ('--servername').
--
set text_editor to "/opt/local/bin/mvim \"+lcd %:p:h\" --servername LOG_PAGE"

-- Should the specified editor be launched from the unix shell?
set should_use_shell to true
---------- END User Configuration ----------------------------------------

---------- ADVANCED (EXPERIMENTAL) ---------------------------------------------
-- For advanced users familiar with the command-line, override the default log
-- directory path. This probably won't be in a public release.
--
-- Grab an exported shell environment variable from a config file to use as the
-- log directory path. For this example, I have a "~/.gtdrc" config file that I
-- source from my "~/.bash_profile" file so that it exportss environment
-- variables relating to my GTD system. That makes those variables available to
-- any of the shell scripts and tools that I use. For instance, when I'm
-- editing files in Vim, I can write paths to other files using one of the
-- environment variables rather than a full or relative path and the 'gf'
-- command will work for jumping to that file. The config file looks like this:
--
--         # ~/.gtdrc
--         #
--         # File locations for GTD documents
--         #
--         export GTD_DIR=$HOME/Documents/org  # GTD root directory
--         export GTD_IN=$GTD_DIR/content      # source/input files
--         export GTD_OUT=$GTD_DIR/html        # generated HTML output files
--         export GTD_LIB=$GTD_DIR/lib         # code library files
--         export GTD_BIN=$GTD_LIB/script      # scripts
--
-- Remove (or comment out) the "(*" and "*)" comment markers below to use this
-- section. Make sure you also configure the two variables for your system.
--(*
--------------- USER CONFIGURATION ----------
-- Path to your config file:
set cfg_file to POSIX path of (path to home folder) & ".gtdrc"
-- The environment variable you're interested in:
set env_var to "GTD_IN"
--------------- END User Configuration ---------

-- Check for environment variable in config file:
set s to "egrep '\\<" & env_var & "=' " & quoted form of cfg_file &
	" > /dev/null 2>&1; echo $?"
set shell_status to (do shell script s) as integer
-- Source the config file and echo the desired variable:
if shell_status is 0 then -- (means that grep found a match)
	set s to ". " & quoted form of cfg_file & " && echo $" & env_var
	set gtd_in_dir to do shell script s
	set log_dir to gtd_in_dir & "/logs/"

	--------------------
	-- OPTIONAL: Override the Text editor to integrate with my GTD system.
	--
	-- This example:
	--	1. Opens the file using MacVim ('mvim' as installed by MacPorts)
	--	2. Switches the local working directory ('lcd') for just that buffer to
	--	    my GTD content directory ($GTD_IN after escaping potential spaces)
	--	3. Gives the MacVim window a name ('--servername').

	----- First, escape any potential spaces in the directory path:
	--
	--set gtd_in_dir to gtd_in_dir & " foo    bar" -- :DEBUG: spaces in path
	--
	set s to "echo " & quoted form of gtd_in_dir & " | sed 's/ \\{1,\\}/\\\\ /g'" -- escape spaces
	set gtd_in_dir to do shell script s
	--
	--log gtd_in_dir -- :DEBUG: need to use 'log' to see the value w/o AppleScript escapes

	----- Finally, set the editor with all of the options:
	--
	set text_editor to "/opt/local/bin/mvim \"+lcd " & gtd_in_dir & "\" --servername GTD --remote-silent"
	--
	--log text_editor -- :DEBUG:
