# set MKS Korn shell environment variables for MS Visual Studio 2019
# Revision history
# 2022-09-04: changed "egrep" to "grep -E"
# 2021-09-26: revised to use Visual Studio 2019
# 2020-05-08: revised to prevent MKS Toolkit from prepending
# UTF-8 signature
# 2016-05-28: initial version

# Microsoft Visual Studio requires that several environment variables
# include many directories if a build is to be done from the command
# line. These variables are normally set by selecting 'Developer
# Command Prompt' on the Windows Start Menu; the shortcut runs a batch
# file that calls several other batch files to set the variables before
# launching an instance of the Windows command interpreter. This
# program calls the Windows command interpreter to run the batch file;
# the resulting values of the variables are echoed and read into the
# shell to set the variables in the shell. For the values to persist,
# this program must be run in the current environment, i.e.,
#
# source setvcvars
#
# or
#
# . setvcvars
