# This GNU Makefile supports different OS and CPU combinations.
#
# You should use it this way :
# [g]make TARGET=os [ARCH=arch] [CPU=cpu] USE_xxx=1 ...
#
# When in doubt, invoke help, possibly with a known target :
# [g]make help
# [g]make help TARGET=linux-glibc
#
# By default the detailed commands are hidden for a cleaner output, but you may
# see them by appending "V=1" to the make command.
#
# Valid USE_* options are enumerated in the "use_opts" variable and are listed
# below. Most of them are automatically set by the TARGET, others have to be
# explicitly specified :

#
# Options can be forced by specifying "USE_xxx=1" or can be disabled by using
# "USE_xxx=" (empty string). The list of enabled and disabled options for a
# given TARGET is enumerated at the end of "make help".
#
# Variables useful for packagers :
# CC is set to "cc" by default and is used for compilation only.

#### Memory usage tuning
# If small memory footprint is required, you can reduce the buffer size. There
# are 2 buffers per concurrent session, so 16 kB buffers will eat 32 MB memory
# with 1000 concurrent sessions. Putting it slightly lower than a page size
# will prevent the additional parameters to go beyond a page. 8030 bytes is
# exactly 5.5 TCP segments of 1460 bytes and is generally good. Useful tuning
# macros include :
# SYSTEM_MAXCONN, BUFSIZE, MAXREWRITE, REQURI_LEN, CAPTURE_LEN.

# without appearing here. Currently defined DEBUG macros include DEBUG_FULL,
# DEBUG_MEM_STATS, DEBUG_DONT_SHARE_POOLS, DEBUG_FD, DEBUG_POOL_INTEGRITY,
# DEBUG_NO_POOLS, DEBUG_FAIL_ALLOC, DEBUG_STRICT_ACTION=[0-3], DEBUG_HPACK,
