| # @BLURB: helper functions to install systemd units |
| # @DESCRIPTION: |
| # This eclass provides a set of functions to install unit files for |
| # sys-apps/systemd within ebuilds. |
| # @EXAMPLE: |
| # |
| # @CODE |
| # inherit autotools-utils systemd |
| # |
| # src_configure() { |
| # local myeconfargs=( |
| # --enable-foo |
| # --disable-bar |
| # ) |
| # |
| # systemd_to_myeconfargs |
| # autotools-utils_src_configure |

| # This function always succeeds, even if systemd is not installed. |

| # @USAGE: unit1 [...] |
| # @DESCRIPTION: |
| # Install systemd unit(s). Uses doins, thus it is fatal in EAPI 4 |
| # and non-fatal in earlier EAPIs. |

| # @USAGE: target service |
| # @DESCRIPTION: |
| # Enable service in desired target, e.g. install a symlink for it. |
| # Uses dosym, thus it is fatal in EAPI 4 and non-fatal in earlier |
| # EAPIs. |

| # to preserve whitespace in paths. systemd_to_myeconfargs() is preferred over |

| # @DESCRIPTION: |

| # scripts to the myeconfargs variable used by autotools-utils eclass. Handles |
| # quoting automatically. |
