"Applet" is a much better name for the external command-line scripts and programs that can be loaded as PBot commands. They will no longer be confused with Perl modules. https://en.wikipedia.org/wiki/Applet

# File: Applets.pm
|
|
#
|
|
# Purpose: Applets are command-line programs and scripts that can be loaded
|
|
# via PBot factoids. Command arguments are passed as command-line arguments.
|
|
# The standard output from the script is returned as the bot command result.
|
|
# The standard error output is stored in a file named <applet>-stderr in the
|
|
# applets/ directory.
