- --disable-debug don't worry about debugging
- --enable-debug set compiler flags for debugging
-
- --enable-shared enable shared libraries
- --disable-shared don't build shared libararies
-
-To change where the library is installed:
-
- --prefix=PATH set the base installation directory
- --libdir=PATH install library files in \${prefix}/\${libdir}
- --docdir=PATH install documentation in \${prefix}/\${docdir}
-
-To change what modules to use:
-
- --enable-modules=[module,[module[,...]]]

-
-To get diagnostic and debug output:
-
- --module-info display more information about modules
-
- --show-arch-info=CPU show more information about a particular CPU
- [$cpus]
-
- --help display this help
- --version display the version of Botan
- --quiet display only warnings and errors
- --trace enable runtime tracing of this program
