Sigma example 3: building template from multiple files

# Σtemplate example 3: building template from multiple files

Please note that block names should be unique within the template even if the template is built from multiple files. Therefore it is usually a bad idea to include one file in two different places, unless this file contains no blocks.

## 1. Using <!-- INCLUDE filename --> within template

This is the way to include a file from within a template, no additional code is required in your script. Note that this creates no blocks except ones already present in main and included files.

## 2. Using addBlockfile()

addBlockfile() creates a new block in place of a variable placeholder.

{addblockfile}

## 3. Using replaceBlockfile()

replaceBlockfile() replaces the existing block with a new content.

### 3.1 Keeping the previously parsed contents

You can keep the parsed contents of the original block and continue iteration over the new one.

- Original block: {item_title}

### 3.2 Discarding the previously parsed contents

Or you can discard the parsed contents and start from scratch (this is the default behaviour).

- {item_title}
