+# LGSM mods_list.sh function
+# Author: Daniel Gibbs
+# Contributor: UltimateByte
+# Website: https://gameservermanagers.com
+# Description: Lists and defines available mods for LGSM supported servers.
+# Usage: To add a mod, you just need to add an array variable into fn_mods_info following the guide to set proper values. 
+# Usage: Then add this array to the mods_global_array.
+# Usage: If needed, you can scrape to define the download URL inside the fn_mods_scrape_urls function.

+	# None of those values can be empty
+	# [index]	| Usage
+	# [0] 	| MOD: separator, all mods must begin with it
+	# [1] 	| "modcommand": the LGSM name and command to install the mod (must be unique and lowercase)
+	# [2] 	| "Pretty Name": the common name people use to call the mod that will be displayed to the user
+	# [3] 	| "URL": link to the file; can be a variable defined in fn_mods_nasty_urls (make sure curl can download it)
+	# [4] 	| "filename": the output filename
+	# [5]	| "modsubfolders": in how many subfolders is the mod (none is 1)
+	# [6]	| "LowercaseOn/Off": LowercaseOff or LowercaseOn: enable/disable converting extracted files and directories to lowercase (some games require it)
+	# [7] 	| "modinstalldir": the directory in which to install the mode ( use LGSM dir variables such as ${systemdir})
+	# [8]	| "/files/to/keep;", files & directories that should not be overwritten upon update, separated and ended with a semicolon; you can also use "OVERWRITE" to ignore the value or "NOUPDATE" to disallow updating
+	# [9] 	| "Supported Engines;": list them according to LGSM ${engine} variables, separated and ended with a semicolon, or use ENGINES to ignore the value
+	# [10] 	| "Supported Games;": list them according to LGSM ${gamename} variables, separated and ended with a semicolon, or use GAMES to ignore the value 
+	# [11]	| "Unsupported Games;": list them according to LGSM ${gamename} variables, separated and ended with a semicolon, or use NOTGAMES to ignore the value (useful to exclude a game when using Supported Engines)
+	# [12]	| "AUTHOR_URL" is the author's website, displayed to the user when chosing mods to install
+	# [13]	| "Short Description" a description showed to the user upon installation
