# Synopsis:

#

# sh build.sh - Build inplace

# sh build.sh test - Build inplace, and run the tests

# sh build.sh wheel - Build a wheel, install, and run the tests

#

# Environment variables:

#

# LIBSSH2_OPENSSL - Where to find openssl

# LIBSSH2_PREFIX - Where to find libssh2

# LIBSSH2_VERSION=<Version> - Build the given version of libssh2

# LIBGIT2_VERSION=<Versoin> - Build the given version of libgit2

#

# Either use LIBSSH2_PREFIX, or LIBSSH2_VERSION, or none (if libssh2 is already

# in the path, or if you don't want to use it).

#

# Examples.

#

# Build inplace, libgit2 must be available in the path:

#

# sh build.sh

#

# Build libgit2 1.1.0 (will use libssh2 if available), then build pygit2

# inplace:

#

# LIBGIT2_VERSION=1.1.0 sh build.sh

#

# Build libssh2 1.9.0 and libgit2 1.1.0, then build pygit2 inplace:

#

# LIBSSH2_VERSION=1.9.0 LIBGIT2_VERSION=1.1.0 sh build.sh

#

# Tell where libssh2 is installed, build libgit2 1.1.0, then build pygit2

# inplace:

#

# LIBSSH2_PREFIX=/usr/local LIBGIT2_VERSION=1.1.0 sh build.sh

#

# Build inplace and run the tests:

#

# sh build.sh test

#

# Build a wheel:

#

# sh build.sh wheel

#
