The solution is not to pre-process 'functions.in' into 'functions', but
to add the new tools to the generated paths.mk and paths.sh, and then to
use ${sed} and ${grep} where needed.
Note that 'sed' is already present in those files, so only grep needs to
be added.
Is there a name which GNU grep is known as on BSD systems? For example,
we have gsed. Do we have ggrep, too?
In which case, we'd need four patches:
- use ${sed} instead of plain 'sed' where appropriate
- add --with-grep to the list of tools we can specify
- add an alternate name for when searching for grep
- use ${grep} instead of plain 'grep' where appropriate
I'll tackle this here.
Sorry for the delay, and thanks for the report.
Regards,
Yann E. MORIN.
