 The MSToolkit is a light-weight C++ library for reading, writing, and manipulating mass spectrometry data. The MSToolkit is easily linked to virtually any C++ algorithm for simple, fast file reading and analysis.

 ### Compiling
 A few hints:
+ * On GNU/Linux, try "make all" to build the library. On VS/Windows, you'll have to build your own solution.
  * Add _NOSQLITE to build smaller library without SQLite. SQLite is only required for special case usage.
- * Add _NO_THERMORAW to build without Thermo file support in Windows. This is not necessary in Linux, where Thermo support is disabled by default.

  * Older versions of MSVC may require building with XML_STATIC declared.
  * Declaring WIN32 may still be required for compiling 64-bit libraries with MSVC.
