# ---- infrastructure to build Go workspaces / projects ----

# gowork is a top-level section representing workspace
#
# users should add `install` field to [gowork] to describe packages they want to
# be installed (+ automatically their dependencies are installed too). e.g.
#
#   [gowork]
#   install =
#       lab.nexedi.com/kirr/neo/go/...
#       github.com/pkg/profile
#       golang.org/x/perf/cmd/benchstat

# should list paths where to search for pkg-config files, e.g. this way:
#
#   [gowork]
#   cpkgpath =
#       ${sqlite3:location}/lib/pkgconfig
#       ${zlib:location}/lib/pkgconfig
#
# It is also possible to specify Go build flags used for compilation e.g. this way:
#
#   [gowork]
#   buildflags = -race
