Comment:
```roff
.TH "DIDDER" "1" "$(DATE)" "didder $(VERSION)" "User Manual"
```
this isn't doing what you think it is. those are `make` variable substitutions.

```suggestion
	sed -i "s/VERSION/${version}/g" didder.1
	_date="$(date --utc --date "@$SOURCE_DATE_EPOCH" "+%B %d, %Y")"
	sed -i "s/DATE/${_date}/g" didder.1
```
this should insert the actual date and version
