+ * Updated 2010-11-10 by Thomas Perl <thp.io/about>:
+ *  - Make it compile on newer versions of Cygwin
+ *  - Convert "/" to "\" (so "dclick ../test.pdf" works)
+ *
  * equivalent of DOS shell "start" command: launches a file using the
  * shell as though it were double-clicked in explorer
  *
- * to build, must link in shell32.lib:
- * cl /nologo dclick.cpp shell32.lib
+ * To build using Cygwin's gcc, simply use:
+ *    gcc dclick.cpp -o dclick
