+$program, a non-interactive utility for checking for available upgrades in
+Python pip requirements files based on pip-tools
+
+Usage: $program [OPTIONS] configuration_directory
+
+$program a non-interactive utility for checking for available upgrades in Python
+pip requirements files based on pip-tools. Utility is written specifically with
+pip-tools in mind, and pip-tools must be available when running the utility.
+
+If you are unfamiliar with pip-tools, please read its documentation first, and
+make sure you fully understand how it works.
+
+Utility accepts a single positionl argument - path to configuration
+directory. Configuration directory should contain one or more sub-directories
+where each sub-directory is treated as describing a separate Python virtual
+environment. This allows the checks to be run for multiple virtual environments
+in a modular manner.
+
+Each sub-directory should contain one or more .in files with corresponding .txt
+file. Base names must match (i.e. if you have production.in, the requirements
+file must be called production.txt).
+
+Utility iterates over each .in/.txt pair, calculates new requirements based on
+the .in file, and diffs this against existing .txt file.
+
+Utility creates copy of existing requirements file, stripping it from all
+comments, then calculates new requirements file (storing result in temporary
+location as well), and runs a diff between them.
+
+If newer pacakges are available that would satisfiy the provided .in file, a
+diff is shown on standard output in addition to a warning message.
+
+$program accepts the following options:
+
+    -V virtualenv
+        Path to virtual environment with pre-installed pip-tools. If specified,
+        the virtual environment will be activated prior to running the utility.
+
+    -q
+        Quiet mode. Output a message only if newer packages are available.
+    -d
+        Enable debug mode.
+    -v
+        Show script licensing information.
+    -h
+        Show usage help.
+
+
+Please report bugs and send feature requests to <branko@majic.rs>.
