 Requirements
 ------------
-You will need a C++ compiler.
+You will need a C++ compiler, (de)compressors for bzip2 and gzip
+formats, and a compressor for the lzip format.
 I use gcc 4.8.1 and 3.3.6, but the code should compile with any
 standards compliant compiler.
 Gcc is available at http://gcc.gnu.org.
