+# The build options are available:
+# clean              Cleans the build directory.
+# -g                 Compile with debug support.
+# -l<library>        Compiles against the shared system version of the specified library.
+# -DLPM_NO_GIT       Compiles without libgit2 support.
+# -DLPM_NO_NETWORK   Compiles without network support.
+# -DLPM_NO_THREADS   Compiles without threading support.
+# -DLPM_VERSION      Sets the specific version.
+# -DLPM_STATIC       Bundles lpm.lua into the binary executable.
