+=head1 NAME
+
+mkdocs-prep - mkdocs preprocessor expanding inline hints and mustache tokens
+
+=head1 VERSION
+
+Version 0.02
+
+=head1 SYNOPSIS
+
+=head1 DESCRIPTION
+
+B<mkdocs-prep> prepares a markdown document for B<mkdocs> processing.
+
+The document is converted using inline hint section to a mustache template
+and resolved using an external set of single-word tokens.
+
+A document section named "Special strings" is parsed for token definitions
+where each line lists a single-word token, a colon, and default string.
+The section is then stripped,
+and all occurences of default strings are replaced with tokens
+wrapped with double curly brackets.
+
+Template tokens are gathered from external config file F<site.mk>,
+where each line lists a token, an equals sign, and replacement string.
+
+Inline defined tokens not declared in F<site.mk> will be prompted for.
+if a value is provided it will be used, and also saved in F<site.mk>.
+If no value is provided then inline default string is used.
+
+Each token in the document,
+wrapped with double curly brackets {{like_this}},
+is replaced (including brackets) with corresponding string.
