=== set declib ===

 '''set declib''' ''LIB<sub>1</sub>'' [ ''LIB<sub>2</sub>'' ''LIB<sub>3</sub>'' ... ]
Sets the decay data library file paths. Input values:

{|
| <tt>''LIB<sub>n</sub>''</tt>
| : library file paths
|}

<u>Notes:</u>

*Decay libraries are standard ENDF format<ref name="endf" /> files containing decay data.
*If the file path contains special characters it is advised to enclose it within quotes.
*A default directory path can be set by defining environment variable <tt>SERPENT_DATA</tt>. The code looks for decay data files in this path if not found at the absolute.
*From version 2.2.0 and on, a default decay data library directory file can be set by defining environment variable <tt>SERPENT_DECLIB</tt>. 
**This file will be used if no other path is given with '''set declib'''.
