### Generating the lexer and parser

# header file creation so we'll use good old make

### Building the jq binary

### Building the manpage

# If ENABLE_DOCS is not set, just copy jq.1.default to jq.1
# The real_docs target succeeds (possibly after building jq.1) only if ENABLE_DOCS is set
# Thus, making "dist" depend on "real_docs" ensures that we never build a tarball with
# a stub manpage.
