\b The /V switch followed by a number between 0 and 4 will set the verbosity of output accordingly. 0=no output, 1=errors only, 2=warnings and errors, 3=info, warnings, and errors, 4=all output.
\b The /P switch followed by a number between 0 and 5 will set the priority of the compiler process accordingly. 0=idle, 1=below normal, 2=normal (default), 3=above normal, 4=high, 5=realtime.
\b The /O switch followed by a filename tells the compiler to print its log to that file (instead of the screen)
\b /PAUSE makes makensis pause before quitting, which is useful when executing directly from Windows.

\b If multiple scripts are specified, they are treated as one concatenated script.
\b On Windows 95, 98 and NT, below normal and above normal process priorities are not available. On those systems, below normal will actually set priority to idle and above normal will set to high.
\S1{usageenvironment} Environment variables
makensis checks a number of environment variables that tell it where to locate the things it needs in order to create installers. These variables include:
