# Description: This script implements a wrapper for any program which does not accept
|
|
# stdin input on most Unix machines. The input to the script is read to a
|
|
# temporary file, and the first argument sets a particular file extension
|
|
# for the temporary file.

# All of the following arguments are read as command to run.

# In perfect world it wouldn't be needed, but some tools (`go vet`, I am looking

# at you) do not fit in line and require filename ending. Otherwise it would be

# simple as

#
|
|
# "$@" /dev/stdin
|
|
#
|
|
# without all that hackery with copying `/dev/stdin`
