+ --with-build-dir=DIR setup the build in DIR
+ --with-local-config=FILE include the contents of FILE into build.h
+
+ --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:

+
+To get diagnostic and debug output:
+
+ --module-info display more information about modules
+
+ --show-arch-info=CPU show more information about a particular CPU

+
+ --help display this help
+ --version display the version of Botan
+ --quiet display only warnings and errors
+ --trace enable runtime tracing of this program
