-transforms a template string to its refined version by substituting its placeholders with concrete values
-
-
-## Building
-
-### Requirements
-
-- shell interpreter
-
-
-### Instructions
-
-- execute `tools/build`
-
-
-## Installation
-
-### Requirements
-
-- shell interpreter
-
-
-### Instructions
-
-- (as `root`) execute `tools/install`
-
-
-## Usage
-
-### Requirements
-
-- Python 3 interpreter
-
-
-### Examples
-
-#### basic
-
-```
-echo '{{flowers}} are {{color}}' | coin -a 'flowers:roses' -a 'color:red'
-
-# roses are red
-```
-
-The same result can be produced by using multiple `coin` calls:
-
-```
-echo '{{flowers}} are {{color}}' | coin -a 'flowers:roses' | coin -a 'color:red'
-```
-
-In some contextes curly brackets might might be reserved or not available for other reasons. This can be mitigated by using different placeholder indicators:
-
-```
-echo '<<flowers>> are <<color>>' | coin -o '<<' -c '>>' -a 'flowers:roses' -a 'color:red'
-```
-
-
-#### file arguments
-
-```
-echo -n "cornflowers" > /tmp/flowers.txt
-echo -n "blue" > /tmp/color.txt
-echo '{{flowers}} are {{color}}' | coin -a 'flowers:@/tmp/flowers.txt' -a 'color:@/tmp/color.txt'
-
-# cornflowers are blue
-```
-
-
-#### data file
-
-```
-echo -e "flowers: daffodills\ncolor: yellow" > /tmp/data.yaml
-echo '{{flowers}} are {{color}}' | coin -d /tmp/data.yaml
-
-# daffodills are yellow
-```
