-# NAME
-
-sttemp - simple template manager
-
-# SYNOPSIS
-
-**sttemp** \[**-h**\]
-
-**sttemp** \[**-e**\] *template* \[*output*\]
-
-# DESCRIPTION
-
-**sttemp** copy file from your template directory and fill all
-substitutions with user input, or environment variables. Template
-directory and substitution pattern described in **src/config.h** file,
-in suckless style. You can use **\~** as **first** symbol of your path,
-for relative path from your home directory.
-
-# OPTIONS
-
-**-h**
-
-: displays help information
-
-**-e**
-
-: use environment variables for fill substitution in template, if
- **sttemp** can\'t find environment variable with needed name, it
- will use user input
-
-**template**
-
-: name of file in your templates directory, which will use to create
- new file
-
-**output**
-
-: name of target file, if omit - **sttemp** will use template name
