Any macro listed in .makeenv is also put in + the environment. + + After loading .makeenv and adding populating the environment, + makeenv will inspect it's environment, makeenv itself is + affected by the environment variables, which also are make(1) + macros; this if you need a specific implementation of make(1) + for a project, it can be specified in the .makeenv file. + + When executng make(1), makeenv may reorder the arguments, and + will put any option listed in .makeenv at the beginning, any + macro listed in .makeenv before the macros in the arguments, + and any target listed in .makeenv before the targets in the + arguments. + + makeenv is designed to be usable in place of make(1), that is, + the user can create add the alias makeenv=make in his shell, + without any adverse affect. makeenv will pass on it's arguments + as is to make(1) (or whichever utility is specified in the + environment variable MAKEENV_MAKE or the environment variable + MAKE) without validation or modifications, if the .makeenv does + not exist. + +OPTIONS + The makeenv utility passes it's options to the make(1) utility + and do not act on any of the it self, however in order to + properly interleave options and operands specified in the + .makeenv file, it have to understand which options take an + argument and which do not. By default, the makeenv utility only + understands the options specified by POSIX, and the argumented + option -W (vendor options), as well as long options that start + with two dashes (--) provided that the same command line + argument contains an equals sign (=). The user can modify the + environment variables to modify how the makeenv utility + understands the options. See the section ENVIRONMENT VARIABLES + for more information. The current version only support options + that consist of a dash (-) followed by any other character and + options that start with two dashes (--), followed by at least + one character, but may not contain an equals sign (=), as these + are treated as delimiters between long options and their + associated argument. + +STDIN + Not used. + +INPUT FILES + None. + +ENVIRONMENT VARIABLES + The following environment variables affect the execution of + makeenv: + + PATH + Default. + + MAKEENV_MAKE, MAKE + The command that shall be invoked by the utility.
