#/bin/sh
# 
# Note: double hash comments indicates help documentation
#
## Syntax: build.sh [OPTIONS]
## 
## Build gridlabd on this local system. You must have run `setup.sh` first.
## 
## Options:
## 
##   -v|--verbose)   Enable output of commands as they are executed
## 
##   -s|--silent)    Disable output to stderr
## 
##   -q|--quiet)     Disable output to stdout
## 
##   --validate)     Enable validation of build (requires --install)
## 
##   --install)      Install build to target folder
## 
##   --system)       Make the install the system default installation
## 
##   --target PATH)  Specify the target folder (default is output of /usr/local/opt)
## 
##   --clean)        Delete all new uncommitted source files before starting build
## 
##   --upload)       Upload installed image to AWS when build is done
## 
##   --release)      Make AWS upload the default image for system/machine type
## 
##   --parallel[=N]) Run the build in parallel if possible. N specifies how many jobs
##                   per CPU. The default is 3 jobs per CPU.
## 
##   --srcdir=DIR    Specify an alternate source directory to use (default is
##                   same as build.sh script) 
##
##   --workdir=DIR   Specify an alternate working directory to use (default is
##                   same as build.sh script)
##
## Environment variables:
## 
##   MAKEFLAGS   Specify additional make options
## 
##   CFLAGS      Specify additional C compiler flags
## 
##   CPPFLAGS    Specify additional C++ compiler flags
## 
##   LDFLAGS     Specify additional linker flags
## 
## Example:
## 
##   A typical first-time build/install command is usually
##
##   $ ./build.sh --parallel --system
##
