## with "-" and join all lines by replacing "\n" with litteral string c-style "\n\t" and
## output it to "version.i.tmp".
##
+## Repeat the same logic for the "version/extra_patches" directory.
+## Data fetched from "version/extra_patches" must be sanitized and
+## formatted.
+## The data is fetched using "ls" with an ignore pattern for the README file.
+## The sanitize step uses sed with a script to replace all
+## non-alpha-numeric values, except " " (space), to "-".
+## The formatting step uses sed with a script to join all lines
+## by replacing "\n" with litteral string c-style "\n\t".
+##
## If we don't have a "version.i" or we have both files (version.i, version.i.tmp)
## and they are different, copy "version.i.tmp" over "version.i".
## This way the dependent targets are only rebuilt when the git version
version.i:
